Can You Bring a Carry-On and a Personal Item?

The Short Answer

Yes — most airlines allow you to bring both a carry-on bag and a personal item on the same flight at no extra charge. The carry-on goes in the overhead bin, and the personal item slides under the seat in front of you.

But not all airlines play by the same rules. Budget carriers like Spirit, Frontier, Ryanair, and Wizz Air only include one small bag for free. If you want to bring anything larger — including a standard carry-on — you pay extra. Understanding the difference can save you a significant amount of money.

What Counts as a Personal Item?

A personal item is the smaller of your two allowed bags. It must fit under the seat in front of you — that's the defining rule across virtually every airline.

Common personal items include:

• Purses and handbags — even large ones, as long as they fit under the seat
• Small backpacks and daypacks — the most popular choice for travelers
• Laptop bags and messenger bags
• Briefcases
• Camera bags
• Small tote bags
• Diaper bags (often allowed in addition to your regular personal item for passengers traveling with infants)

The practical test: if you can slide it under the seat without forcing it or blocking your legroom, it counts as a personal item.

Personal Item Size Limits by Airline

Airlines publish maximum dimensions for personal items, though enforcement varies. Below are the published limits for major carriers:

Tip: Dimensions listed are typically length x width x height (L x W x H) and include handles and wheels. A bag that measures right at the limit may still be rejected if it looks obviously overstuffed.

Airlines That Charge for Carry-Ons (Not Personal Items)

This is where travelers get caught off guard. Several airlines advertise "free bags" but the free bag is only the personal item — the overhead bin bag costs extra.

Spirit Airlines

Spirit includes one personal item (up to 18 x 14 x 8 inches) for free with every ticket. A carry-on bag for the overhead bin is not included and costs $45 to over $100 depending on when you buy it — prices are lowest when added during booking and highest at the gate.

Frontier Airlines

Similar to Spirit: your personal item is free, but overhead bin access requires purchasing a carry-on add-on starting around $30–$99 depending on route and timing. Frontier's "WORKS" bundle includes bags and other perks for a flat fee.

Ryanair

Ryanair includes one small bag (40×30×20 cm) under the seat for free. To bring a larger carry-on in the overhead bin, you need to add Priority Boarding, which typically costs €6–€30 per flight and includes overhead bin access plus a 10 kg carry-on.

Wizz Air

Wizz Air includes one small cabin bag (40 x 30 x 20 cm) for free. A larger carry-on for the overhead bin costs extra — either purchased as a carry-on add-on or included with WIZZ Priority. Prices typically start around €8–€16 per flight.

What to Pack in Your Personal Item

Since your personal item stays accessible during the flight (unlike a checked bag or overhead bin bag you may not be able to reach), use it strategically.

Pack your personal item with:

• Laptop or tablet and chargers
• Medications and anything you might need quickly
• Passport, boarding pass, travel documents
• Headphones and in-flight entertainment
• A change of clothes (in case checked bags are delayed)
• Snacks and a refillable water bottle (empty through security)
• Wallet, keys, and valuables
• Anything you need during the flight itself

Save bulkier items — clothing, shoes, toiletries — for your carry-on or checked bag.

Tips for Maximizing Your Personal Item Allowance

Use a soft-sided bag. Soft fabric bags compress and flex to fit under the seat much more easily than rigid-sided luggage. A semi-structured backpack or packable tote can hold significantly more than its dimensions suggest.

Pack your personal item last, with in-flight items on top. You want your essentials immediately accessible at your seat without digging through the bag.

Choose a backpack over a rigid case. Backpacks distribute weight better, are easier to carry through airports, and can be squeezed into tighter spaces under the seat than structured briefcases.

Know the under-seat dimensions on your specific aircraft. Under-seat space varies by aircraft type and seat row. Bulkhead seats (first row of a cabin section) often have no under-seat storage — in that case, your personal item has to go in the overhead bin.

Don't overstuff. A visibly bulging personal item may be flagged even if it technically fits the published dimensions. Keep it tidy.

The Bottom Line

Most major full-service airlines (Delta, United, American, Southwest, JetBlue, Alaska, British Airways) allow one carry-on plus one personal item with standard tickets. Budget airlines (Spirit, Frontier, Ryanair, Wizz Air) include only one small bag for free — a personal item that goes under the seat. If you want overhead bin access on a budget carrier, expect to pay.

Before you fly, check the specific policy for your airline and ticket class. Basic Economy tickets on full-service carriers sometimes reduce your allowance to personal item only, matching what budget airlines charge extra for.
