Frequently Asked Questions (FAQ)
Common questions about airline baggage rules, fees, and travel policies.
Standard domestic carry-on size is 22 × 14 × 9 inches (56 × 36 × 23 cm) including handles and wheels. Limits vary by airline and ticket class — Southwest allows 24 × 16 × 10 inches, while budget carriers charge for overhead bags entirely. Always confirm your exact allowance on your airline’s official baggage page before travel.
Airlines may enforce carry-on size limits during boarding. If a bag exceeds the allowed dimensions, it may need to be checked in, sometimes with an additional fee. Measuring your luggage before travel can help reduce this risk.
Gate agents may require it to be checked before boarding, with fees typically ranging from $35 to $75 depending on the carrier. Soft-sided bags that compress slightly fare better. Most airports have physical bag sizers at the gate — if it does not fit, it will be checked on the spot.
The overweight baggage policy dictates the penalty for exceeding the weight limit. Excessive baggage charges apply when you exceed the number of bags allowed on the plane.
When a journey includes multiple layovers, baggage rules may differ for each airline involved. Reviewing the baggage policies for all flights in your itinerary can help you understand possible allowances and fees.
An overweight fee applies when a single bag exceeds the weight limit — usually 50 lbs for Economy. An excessive baggage charge applies when you check more bags than your ticket allows, such as a third or fourth bag. Both charges can apply to the same bag at the same time.
