Baggage rules vary wildly between airlines, and getting them wrong can cost you anywhere from $30 to $300 at the airport. Here's everything you need to know about carry-on bags, checked luggage, weight limits, and fees across major airlines in 2026.
Carry-On Baggage Rules
Most airlines allow one carry-on bag plus one personal item (purse, laptop bag, or small backpack). However, the size limits differ:
- Most full-service airlines: 22 x 14 x 9 inches (56 x 36 x 23 cm) and up to 7–10 kg
- Budget airlines (Ryanair, Spirit, Wizz Air): Often smaller limits — and some charge extra for overhead bin access, limiting free passengers to a small personal item only
- Asian carriers (ANA, Singapore Airlines, Cathay): Typically generous at 7 kg for economy, sometimes 2 bags for business class
The most common mistake travelers make is assuming carry-on rules are universal. Always check your specific airline's policy before packing.
Checked Baggage Fees and Weight Limits
Checked bag fees have become a major revenue source for airlines. Here's the general landscape in 2026:
- US domestic (major carriers): $35–$45 for the first checked bag, $45–$55 for the second
- Budget carriers: $30–$70+ depending on when you pay (online vs. airport)
- International long-haul: Most full-service airlines include 1–2 checked bags in the fare (23 kg each for economy)
- Middle Eastern carriers (Emirates, Qatar, Etihad): Typically generous — 30 kg for economy, 40 kg for business
Weight limits are strictly enforced. Overweight bags typically incur fees of $50–$200 per bag. If your bag exceeds 32 kg, most airlines will refuse to accept it entirely.
What to Do If Your Luggage Is Lost or Delayed
- Report immediately: File a Property Irregularity Report (PIR) at the airline's baggage desk before leaving the airport
- Keep your claim number: You'll need it to track your bag and file for compensation
- Ask about amenity kits: Airlines often provide toiletries and basic items while your bag is missing
- Save receipts: If you need to buy essentials, keep all receipts — airlines reimburse reasonable expenses
- Know the timeline: Bags are considered "delayed" for 21 days. After that, they're officially "lost" and you can claim full compensation — up to approximately $3,800 for international flights under the Montreal Convention
Frequently Asked Questions
Can I avoid checked bag fees?
Yes. Options include: packing in carry-on only, getting an airline credit card (many waive bag fees), achieving elite frequent flyer status, or booking a fare class that includes bags. Some airlines like Southwest still include 2 free checked bags with every ticket.
What happens if my bag is overweight at check-in?
You'll be asked to either pay the overweight fee (typically $50–$200), redistribute items into another bag, or remove items. Keeping a portable luggage scale in your bag can save you from surprises at the counter.
Are there items I cannot pack in checked luggage?
Yes. Lithium batteries, e-cigarettes, lighters, and flammable items must go in carry-on, not checked bags. Valuables, medications, and travel documents should also always be in your carry-on.
