Choosing An 18x14x8 Bag To Avoid Paying Luggage Fees

In the past, most airlines allowed travellers to bring one carry-on bag and one personal item as hand luggage.

However, several airlines have begun to charge additional bag costs for taking a carry-on bag, leaving just the under-seat personal item included in the basic bare price. This forces travellers to look for a bag that measures 18x14x8 inches in order to avoid paying the additional fees.

This essay looks at 18 x 14 x 8 bags that may be used as Frontier or Spirit airline luggage. If you often fly on low-cost airlines, these bags will save you money in the long term. Simply place your suitcase beneath your seat to avoid penalties and long lines at the baggage claim.

Finding a suitable bag this size is a minefield since luggage companies lie about bag sizes and conveniently ignore basics like wheels and handles.

Because budget airlines are anxious for customers in order to make more income, you must be extremely cautious that the quoted sizes are the actual ones. Don’t worry, our offerings have you covered.

Let’s get started.

Wheeled Luggage 18 x 14 x 8

A bag that fits beneath the seat isn’t as compact as you may assume (see the graphic below). With proper planning, you can bring all you need for a short vacation.

These early items are smaller-sized rolling bags with wheels and a telescoping handle, similar to standard carry-on baggage.

When it comes to measuring baggage, wheels are important. Spirit Airlines uses a slot in its sizer that excludes the handle but counts the wheels.

16 Inch Kenneth Cole Reaction

The 16-inch Reaction is a four-wheeled spinning personal item bag designed to fit beneath aircraft seats.

It has an outside dimension of 17.75 x 13.25 x 8 and hence falls just short of the 18x14x8 restriction.

It weights 5.95 pounds.

Spinner baggage is extremely manoeuvrable due to the ability of the wheels to roll in all directions. They are excellent bags for wheeling while upright, which is useful if you are travelling slowly in a line.

The spinner design is particularly handy while travelling through busy locations since it allows you to keep the bag upright and close to your body rather than dragging it behind you.

So far, so good…

However, the spinning wheels come at a cost because airlines consider wheels to be part of your size allowance. There is a significant gap beneath the Kenneth Cole’s wheels. We don’t want to waste any of our allowed space because a personal item is already smaller than a carry-on.

A flawless 18 x 14 x 8 inch rectangle has a volume capacity of around 33 litres. However, by choosing a spinner design, this Kenneth Cole bag ‘wastes’ 4 inches.

The inside dimensions of the main compartment are merely 14.0 x 11.5 L x 7.3, which is only 19 litres, considerably short of the 33 litres that you may potentially utilise.

If you must have spinning wheels, the Kenneth Cole is an excellent option. Otherwise, an 18x14x8 bag with a different design will provide you extra room.

Under Seat American Tourister

Simply looking at the images demonstrates that this American Tourister does not squander room beneath.

This bag completely fits the Spirit sizer and has no protruding wheels.

Of course, because it has two wheels, you’ll have to drag it behind you. You won’t be able to wheel this bag upright either.

However, if you are simply going with a personal item and want to make the most of an 18x14x8 inch allotment, this bag will do the job flawlessly.

The money you’ll save by not paying baggage fees will pay for this bag after just two or three flights, plus it’s well-made, so it should last a long time.

Using a rolling luggage like this feels quite similar to using a regular-sized carry-on. Yes, it’s a little smaller, but you can still pack clothing for 5 – 7 days, especially if you employ compression packing cubes and other light-traveling strategies.

If your normal carry-on is a spinner with protruding wheels, the capacity of this American Tourister bag will be similar to that of a spinner carry-on.

Yes, I understand that spinner wheels are useful. But are they great enough to warrant paying Spirit Airlines baggage fees to obtain them?

No, thank you! I’ll just pull my suitcase behind me to save money!

Blue Boarding

Another two-wheeled alternative is the BoardingBlue. It measures 16.5 x 13.5 x 7.5 inches and hence falls inside Spirit Airlines’ size restrictions.

By making the bag a bit smaller, BoardingBlue has created a bag that works not just with Spirit and Frontier, but also with Southwest and JetBlue. These airlines offer slightly reduced personal item size limitations, however at the time of writing, they do not charge for carry-on size baggage, so making the most of your personal item allowance isn’t as important.

United is the only major airline with which BoardingBlue does not operate effectively. The combined personal item size is significantly less.

So, if you want an under-seat bag that you can use with most US airlines, this boarding blue would be a nice alternative for you.

It weighs 4.35 pounds and carries two handy front compartments for travel papers.

While the BoardingBlue is reasonably priced, it is a lesser-known brand with uncertain construction quality and consistency.

Backpacks measuring 18 x 14 x 8 inches

For constrained spirit aeroplane luggage, a backpack might be a nice personal item. Because the Spirit personal item size is relatively large, most backpacks will work.

It’s far easier to squash a backpack than it is to squash a luggage. If your backpack has to be a bit smaller to travel on JetBlue or Southwest, simply don’t load it as full.

If you prefer hard shell baggage, bear in mind that all soft bags perform better with airport sizers. Although having soft-sided baggage helps, they still have stiff frames, and backpacks and soft duffel bags devour airline sizers for breakfast.

The disadvantage of a backpack over rolling baggage is that it must be carried. If you decide to choose the backpacking route, be sure you are physically fit enough to carry your stuff.

We looked for 18 x 14 x 8 backpacks that were near to the size constraints to maximise capacity.

Weekender Backpack by AmazonBasics

The Weekender is 18 x 12.5 x 7.8 inches, making it an ideal size for Spirit or Frontier Airlines.

In fact, because it can be squashed, it will be ideal for use as an underseater on most airlines.

If you’re looking for an 18 x 14 x 8 backpack, the size isn’t far off. It does not add excessive weight to your back because it weighs only 3.7 lbs.

Weekender, in my opinion, is a bit deceptive. It should be dubbed a Long Weekender. You can easily put 5 days of clothing in this, and maybe 7 days if you travel light.

Of course, because the weight is on your back, you may believe that two or three days’ worth of clothing is plenty. Everything will be determined by how far you want to walk and your level of physical condition.

Backpack Hanke 18″

The dimensions of the Hanke are 18.4 x 12.2 x 7.8 inches.

Don’t be concerned that 0.4 inch is too large. If it’s not so full that the zips are bursting, you can simply crush this bag to fit.

Backpacks of this size are ideal for a short journey for one major reason.

You can fill them with enough clothing for a short vacation. If necessary, you may do some washing in the hotel room sink to keep you going for a few days longer.

However, if you get at your location and want to go sightseeing or on a day walk, this backpack is not too large to serve as a day pack.

Your 18x14x8 rolling suitcase will only be handy for travelling from house to hotel, but this backpack will be used every day of the vacation!

The Hanke also boasts anti-theft capabilities that can provide added piece of mind at the airport or throughout town.

Vintage Canvas Backpack Odyseaco Montera

The Odyseaco is another huge backpack that works well as a Spirit personal item.

The dimensions of this bag are 18 x 14 x 8 inches.

The bag has a rough antique appearance and is constructed of strong canvas.

When it comes to backpacks, any backpack that falls within the size restrictions will suffice.

Because you will be wearing your bag about town, personal style is far more essential than luggage.

So, if you think the backpack option will work for you, go ahead and search through all of the backpack sizes until you find one that looks the part and suits your personality.

Duffel Bags 18 x 14 x 8

A backpack is ideal since it frees up your arms, but a duffel bag is also an excellent personal item.

They are frequently more rectangular and make appropriate use of the available space.

You may also make them smaller by not overpacking and then compressing them down to fit if they are too big. They do not have the same rigid build as rolling baggage.

Duffel bags might appear nicer when combined with a suit when travelling for business. Something about a dressed businessman with a bag simply seems off.

In this case, a duffel bag is a smart alternative to consider.

The Maxlite 5 Duffel from TravelPro

For more professional-looking baggage, the Maxlite 5 Duffel is a fantastic choice.

It is 18 x 11 x 8 inches and fits beneath the seat of the Spirit or Frontier.

TravelPro claims a capacity of 28 litres, which is close to the theoretical limit of 33 litres.

It’s waterproof and comes with a baggage strap for attaching it to a bigger suitcase.

It comes in a variety of hues, so you should be able to pick one that suits your preferences.

Duffel Bags for Personal Items

This bright duffel bag is virtually rectangular, making effective use of the under-seat storage space.

It is 17 x 13 x 7 inches and will suit Spirit, Frontier, American, Delta, and JetBlue but will be too big for United.

Because there is no cushioning, you would need to use a laptop sleeve to safeguard your computer.

There are several duffel bags that fit beneath aircraft seats, and like backpacks, your duffel bag selection will be based mostly on personal aesthetic preferences.

Rather than attempting to persuade you that a single duffel bag is the optimal bag for Spirit Airlines, I would just suggest that you explore through duffel bags in various sizes until you locate one that you think looks great.

Narway Travel Duffel, Foldable

The Narway is a compact foldable design. This type of luggage often works best when accompanied with a carry-on.

If you generally travel with a full-size carry-on but occasionally fly with Spirit or Frontier, something like this might be handy when you return to full-service airlines like American Airlines or United Airlines.

You may store this folded in your carry-on as emergency supplementary baggage. You may connect this bag to a rolling suitcase using the luggage strap.

If you frequently fly with Spirit or Frontier, you should get a more sturdy bag. However, if you just plan on taking a few flights with Spirit, this folding travel duffle would be a nice alternative to consider.

There is no cushioning for a laptop, so if it is essential to you, you should pack your laptop in a cushioned laptop sleeve.

The Narway is reasonably priced and may come in helpful down the line.

How large is an 18 x 14 x 8 bag?

The standard carry-on dimensions are 22 x 14 x 9 inches, which equates to 2772 cubic inches or 45 litres. Many airlines in the United States are like this.

The size restrictions for personal goods differ from airline to aircraft. United is the most stringent, but most other airlines consider a personal item to be 18 x 14 x 8 inches or less.

Importantly, both the Spirit and the Frontier personal item sizes are 18 x 14 x 8. These are the only two airlines that do not include carry-on luggage in the base ticket price.

A suitcase measuring 18 x 14 x 8 measures 2016 cubic inches or 33 litres.

A bag measuring 18 x 14 x 8 inches is roughly one-third the size of a standard carry-on luggage.

You can still fly with an 18 x 14 x 8 suitcase without paying extra for a larger carry-on or checked luggage if you pack smartly and learn how to travel light. This is especially true if you are going on a short trip, like as a weekend getaway.

Is a backpack spirit-free?

Your backpack will be free as long as it is less than 18 x 14 x 8 inches in size. Most typical school or sports backpacks are this size, however some huge travel backpacks are larger.

There is no replacement for measuring your bag to verify if it is the correct size.

Spirit Airlines is how rigorous about personal item size?

Spirit Airlines’ business strategy requires them to be highly tight on the size of your personal item.

If your personal item bag does not fit in the sizer, you will be charged an additional fee. If this happens at the airport, you may be surprised by their pricing; fortunately, your blood pressure is under control!

The Decision

A nice 18 x 14 x 8 spirit bag will save you between $26 and $55 every trip by allowing you to avoid paying for a carry-on or checked luggage.

With the exception of United, they are also excellent carry-on bags for practically all other carriers.

Hopefully, the information in this page will provide you with some food for thought while you seek for a nice 18x 14x 8 travel bag.
