Flying with Delta Air Lines can be a smooth and enjoyable experience—especially when you know exactly what you can and can’t bring on board. One of the most common points of confusion among travelers is understanding Delta’s personal item size. Whether it’s your backpack, purse, or laptop bag, getting this right can make the difference between a stress-free boarding experience and an unexpected gate check.
In this guide, we’ll break down Delta’s personal item rules in simple, conversational language. You’ll learn what counts as a personal item, the exact size limits, what fits under the seat, and some real-world tips to help you pack smart.
What Is a Personal Item on Delta Air Lines?
Let’s start with the basics. When you fly with Delta, you’re allowed to bring two items on board:
-
One carry-on bag, which typically goes in the overhead bin.
-
One small personal item that comfortably slides under the seat in front of you, keeping your essentials within easy reach throughout the flight.
Think of your personal item as your travel buddy—it’s the bag you’ll keep closest to you, filled with essentials you’ll want during the flight.
Typical examples of personal items include:
-
A purse or handbag
-
A laptop bag or briefcase
-
A small backpack
-
A camera bag
-
A diaper bag
If it fits under the seat and doesn’t bother the person next to you, it’s usually acceptable.
The Official Delta Personal Item Size
Unlike the carry-on bag, which has very specific dimensions (22 x 14 x 9 inches), Delta is a bit more flexible with personal items. The airline doesn’t publish a strict measurement for personal items on its website, but the general guideline is that it must fit under the seat in front of you.
However, from practical experience and industry standards, the best size to aim for is around 18 x 14 x 8 inches (45 x 35 x 20 cm).
This size will fit comfortably under most Delta aircraft seats, including narrow-body and regional jets.
Why the Under-Seat Fit Matters

Delta’s personal item policy is built around safety and comfort. Anything you bring under the seat must not block the aisle or prevent you (or the person next to you) from stretching your legs safely.
If your personal item is too large to fit under the seat, the flight attendants might ask you to store it in the overhead bin—or even check it if the cabin is full.
Here’s a good rule of thumb: if you can slide it under your seat and still have a bit of foot space left, it’s perfect.
Comparing Delta’s Personal Item Policy with Other Airlines
It’s always smart to compare. Here’s how Delta stacks up against a few other popular airlines:
| Airline | Personal Item Size (inches) | Notes |
|---|---|---|
| Delta Air Lines | ~18 x 14 x 8 | Must fit under seat |
| American Airlines | 18 x 14 x 8 | Similar to Delta |
| United Airlines | 17 x 10 x 9 | Slightly smaller |
| Southwest Airlines | 16.25 x 13.5 x 8 | A bit tighter |
| JetBlue Airways | 17 x 13 x 8 | Similar limit |
As you can see, Delta is among the most flexible major U.S. airlines when it comes to personal item sizes.
What Fits Under the Seat on a Delta Plane?
The exact under-seat space can vary depending on the aircraft model and seat type. Generally, you can expect:
-
Delta mainline aircraft (like Boeing 737 or Airbus A320): These have a moderate amount of space under each seat. A small backpack or medium tote will fit easily.
-
Delta regional jets: Space is more limited here. You’ll want a compact bag, laptop sleeve, or smaller purse.
-
Delta Comfort+ or First Class: More legroom usually means more space for a slightly bulkier personal item.
If you’re unsure, aim for a bag that’s soft-sided and flexible—it can squish a bit to fit if necessary.
What Counts as a Personal Item vs. a Carry-On?

It’s easy to confuse these two, especially when you’re packing light.
Here’s how to tell the difference:
-
Carry-on bag: Usually a small suitcase or duffel that goes in the overhead bin.
-
Personal item: Smaller and must fit completely under your seat.
For instance, if you’re bringing a rolling suitcase and a backpack, the suitcase counts as your carry-on, and the backpack is your personal item. But if you bring two backpacks—one large and one small—the larger one may be treated as your carry-on.
Tips for Choosing the Perfect Delta Personal Item
Packing smart starts with the right bag. Here’s how to choose one that checks all the boxes:
1. Measure Before You Fly
Use a tape measure to confirm your bag’s dimensions. If it’s over 18 x 14 x 8 inches, it might not fit comfortably under the seat.
2. Go for Flexibility
Soft-sided bags or backpacks are ideal because they can squish into smaller spaces.
3. Pick Something with Compartments
Choose a bag with multiple pockets to keep travel essentials like your passport, headphones, snacks, and chargers organized.
4. Consider the Weight
Delta doesn’t have a strict weight limit for personal items, but remember—you’ll need to lift it yourself and keep it by your feet.
Packing Smart: What to Put in Your Personal Item
Your personal item is like your in-flight survival kit. Here are essentials to keep inside:
-
Travel documents: Passport, boarding pass, ID.
-
Electronics: Laptop, tablet, chargers, headphones.
-
Comfort items: Travel pillow, light blanket, eye mask.
-
Snacks and water bottle: Hydration and munchies are a must.
-
Personal care: Lip balm, sanitizer, wipes, and medications.
A good metaphor? Think of your personal item as your “mini home office” or “comfort kit” for the skies—it should hold everything you’ll want easy access to mid-flight.
What Happens if Your Personal Item Is Too Big?

If your personal item doesn’t fit under the seat, don’t panic—but be prepared.
A gate agent or flight attendant may ask you to store it in the overhead bin. If the bins are already full (which happens often on full flights), you might have to check it at the gate.
To avoid this, test your bag at home. Slide it under a chair or small table to get a realistic idea of how it fits.
Delta’s Exceptions and Special Items
Some items don’t count toward your carry-on or personal item limit. These can include:
-
A coat or jacket
-
Umbrella
-
Duty-free items
-
Assistive devices, like wheelchairs or crutches
-
Child safety seats or strollers
So even if your hands are full, you may still be within Delta’s policy if these are your extras.
Flying International? Here’s What to Know
Delta’s personal item rules are generally consistent across domestic and international flights. However, on smaller aircraft used for connecting flights or international routes, overhead bin and under-seat spaces can be tighter.
If you’re flying internationally, make sure your personal item is compact and flexible—international flights tend to have stricter boarding and luggage enforcement.
Real Traveler Experiences: What Works Best
Frequent Delta flyers often recommend medium-sized backpacks (like 20L–25L) or slim laptop bags. Brands such as Samsonite, Travelpro, and Tumi offer excellent models designed with airline dimensions in mind.
One traveler compared packing the perfect personal item to fitting together a jigsaw puzzle—every item needs to have its place. Once you find the right balance, travel becomes much smoother.
Final Thoughts: Travel Light, Travel Smart
Understanding Delta’s personal item size is about more than just numbers—it’s about convenience, comfort, and confidence. When you pack right, you avoid last-minute stress at the gate and keep everything you need right by your side.
Think of your personal item as your travel lifeline—it’s where your essentials live during the journey. Choose wisely, pack thoughtfully, and you’ll enjoy a smoother flight every time.
