Airline carry-on rules have evolved in 2025—some for convenience, others to squeeze in extra fees. If you want to avoid last-minute surprises at the gate (and keep your packing stress-free), you need to know the latest guidelines. Here’s a breakdown of the new carry-on rules, plus packing hacks from frequent travelers that will save you time, space, and money.
1⃣ Carry-On Size & Weight Limits 
Most US airlines still allow one carry-on bag up to 22 x 14 x 9 inches plus one personal item, but weight restrictions are becoming more common internationally. Always check your airline’s policy before packing—some now enforce 7kg (15 lbs) limits even for carry-ons.
2⃣ Personal Item Rules 
Your personal item (like a backpack, tote, or laptop bag) must fit under the seat in front of you. Airlines are stricter than ever, so oversized “personal items” may get checked at the gate with added fees.
3⃣ New Liquid Allowances 
While the 3-1-1 liquid rule (3.4 oz bottles, 1 quart-sized bag) still applies in most countries, some airports are testing scanners that allow larger liquids. Until these are widespread, stick to travel-sized toiletries to avoid confiscation.
4⃣ Electronics & Battery Rules 
Power banks must be in your carry-on, not checked luggage. Airlines are also asking passengers to remove larger electronics during security screening unless you have TSA PreCheck.
5⃣ Packing Hacks to Maximize Space 
-
Roll, Don’t Fold: Rolling clothes saves space and reduces wrinkles.
-
Use Packing Cubes: Keeps items organized and compresses clothing.
-
Wear Bulky Items: Jackets, boots, and sweaters should be worn to free up space in your bag.
-
Layer Your Outfits: Pack versatile pieces that can be mixed and matched.
6⃣ Avoiding Gate-Check Fees 
Arrive early and board as soon as your group is called—overhead bins fill fast. Once they’re full, airlines may require you to check your carry-on for a fee (unless it’s included in your fare class).
