How Strict Is Delta With Personal Item Size?

So the main question is, since Delta does not have any specific dimensions, how to know what will fit under the seat?

Delta has more than 20 different types of aircraft, but the under-seat space for almost all Delta airplanes is approximately 18” x 11” x 11” (the size required by Delta for a pet carrier to be placed under the seat).

Delta may be strict with personal items if they look too big, so rather than specifying a common size, they tend to give passengers flexibility to choose their items wisely.

The usual items like a laptop bag, purse, or small backpack mentioned on Delta’s website are all within a standard size.

Additional Personal Items For Free

In addition to your personal item, you can also bring the following items with you free of charge:

  • A jacket / coat
  • A small umbrella
  • Food or drink purchased past the security checkpoint
  • Duty-free merchandise
  • Special items like strollers, wheelchairs, child safety seats, or assistive devices like crutches

My Personal Item Is a Bit Oversized. What Will Happen?

If your personal item is slightly oversized, do not worry, especially if it is a soft-sided small bag.

You can still pad it down and make it fit under the seat in front of you.

The only time this might be an issue is when your personal item is way too large.

I usually travel with a small suitcase and a small backpack in which I placed all my personal items.

It seems a little oversized, but it fits perfectly in the sizer.

How to Take More and Make the Most of My Personal Item Space?

To make the most out of your free baggage allowance (carry-on or personal item), you can always wear some of your heavier or bulkier clothing as you go through the gate and place your other essentials in your personal item.

Think coat with deep pockets if you’re really looking to make the most of your hard earned cash.

This will give you more room to pack your essentials items for your trip.

Is a Backpack a Personal Item on Delta Airlines?

Yes, if the backpack can be stowed properly under the seat in front of you. However, if your backpack has the following size 22” x 14” x 9” (56 cm x 35 cm x 23 cm), it will be considered a carry-on bag.

Tweet exchange where Delta confirms that a backpack counts as a personal item if it fits under the seat.

In that case, you may need to bring another smaller item to be placed under the seat.

Delta Carry-on Policy and Restrictions

Delta specifies its carry-on baggage size as follows:

  • Combined dimensions (length + width + height) of baggage must not exceed 45 linear inches (114 cm).
  • Individual length, width, and height measurements may not exceed 22” x 14” x 9” (56 cm x 35 cm x 23 cm).
  • These measurements include any handles or wheels, but do not apply to small musical instruments that fit in the overhead or under-seat space.

Delta Airlines Liquids

Like all other airlines in the US, Delta allows liquids in your personal item in containers less than 3.4 oz (100 ml).

They must be placed in a transparent, quart-sized bag.

For more information, please head to this page on the Transportation Security Administration website, which covers liquids, gels, and aerosols in more detail.

Is Delta Strict With Personal Item Size (Reddit)?

For a seamless flight, carefully reading Delta’s personal item policy will give you the advantage of knowing whether Delta is strict with personal items.

Pick a perfect and compliant bag wisely and stick with the airline’s luggage limits so you won’t be surprised by the hefty luggage fees.

Reddit thread where a user asks if a 20 × 12.2 × 5.7 inch bag is acceptable as a personal item for a flight. Replies note that personal items should fit under the seat and that a flexible bag might be okay.

Final Thoughts

The Delta personal item size is a bit of a gray area.

They have no official size listed, which can feel both freeing and frustrating at the same time.

On one hand, it gives you flexibility if your bag fits under the seat, you’re usually fine.

On the other, it leaves you guessing whether Delta is being practical by not enforcing strict limits or just making things more confusing than they need to be.

I hope this helps

Happy travels
