Delta Personal Item Size (2026)

Delta personal item size under the seat, how it pairs with the free 22×14×9 carry-on, and Basic Economy notes. Official Delta sources linked.

Quick answer

Delta’s personal item must fit under the seat. The airline publishes no L×W×H in inches or centimeters. Official examples only: purse, briefcase, small backpack, belt or fanny pack, camera bag, diaper bag, laptop bag, or something similar or smaller. It is free with one carry-on on every fare, including Basic. United (9 × 10 × 17 in) and Frontier (18 × 14 × 8 in) numbers are not Delta’s.

Free and paid

Personal item: always free when it fits under the seat.

Full carry-on: also free on all fares, including Basic. That is the key contrast with United Basic Economy (personal item only on most domestic routes).

Checked bags: paid on typical domestic Main or Comfort trips ($45 first, $55 second, and higher for extra pieces) unless a status, card, or military waiver applies. Full details are on Delta baggage fees.

Other free extras Delta typically lists (not a second personal item): jacket or umbrella; food or drink purchased after security; sealed duty-free; strollers, wheelchairs, car seats, and assistive devices per the official page.

Gotchas

  • No published L×W×H. Blogs that list exact “Delta personal item” inches are often copying United or Frontier. Delta’s rule is under-seat fit plus examples.
  • Soft bags that look small empty can fail once packed. If it will not slide under the seat, it may be refused as a personal item.
  • Delta Connection (50 seats or less): only personal items stay onboard. Carry-ons get a pink Gate Claim or Planeside tag (free). On those flights the under-seat bag is your only cabin bag, so pack essentials there.
  • United’s $75 gate fee for a failed personal item is not a Delta rule. Delta does not publish that fee for personal-item failures.
  • The carry-on size (22 × 14 × 9) is not the personal-item limit.

Avoid fees

  1. Choose a slim under-seat bag and measure it packed, not empty.
  2. On Connection regional jets, put medications, docs, chargers, and a change of clothes in the under-seat bag.
  3. On mainline flights, use your free overhead carry-on when you need more space. It is still free on Basic.
  4. For checked-bag dollars, use baggage fees.

Bags that fit

Delta does not publish official personal-item inches, so do not treat any bag as “official Delta dimensions.” Look for slim under-seat backpacks and totes marketed to fit under most airline seats, then test under your own seat pitch when you can.

Suggestion 1: under-seat backpack
A compact daypack or “personal item” backpack with a flat profile. Prefer bags that publish packed external dimensions and a soft shell that compresses. Look for wording like “designed to fit under most airline seats,” not “Delta official size.”

Suggestion 2: slim tote or laptop bag
A structured laptop bag or slim tote that matches Delta’s example list. A modest packed depth helps it clear the seat rail. If it only fits overhead, it is your carry-on, not your personal item.
