Understanding Airline Carry-On Policies
Dimensions Include Everything
When airlines list maximum dimensions, they mean total size including wheels, handles, and external pockets. A bag marketed as "22 inches" often measures 23-24" including wheels. Always measure your bag fully assembled.
Basic Economy Restrictions
Many legacy carriers (American, Delta, United) restrict Basic Economy fares to a personal item only - no overhead bin access. If you need a carry-on, you'll pay extra or book a higher fare class.
Budget Carrier Fees
Spirit, Frontier, and other ultra-low-cost carriers charge for carry-on bags. Only a personal item (under-seat bag) is included free. Buying carry-on access at booking is typically cheaper than at the gate.
Regional Jet Considerations
Even with compliant carry-ons, flights on small regional jets may require gate-checking due to limited overhead bins. The airline will gate-check your bag free and return it planeside upon arrival.
Checked Bag Fees
| Airline | 1st Checked Bag | 2nd Checked Bag | Weight Limit |
|---|---|---|---|
| American | $35 | $45 | 50 lbs |
| Delta | $35 | $45 | 50 lbs |
| United | $35 | $45 | 50 lbs |
| Southwest | Free | Free | 50 lbs |
| JetBlue | $35 | $45 | 50 lbs |
| Spirit | $31-69 | $41-79 | 40 lbs |
| Frontier | $39-69 | $49-79 | 50 lbs |
Fees vary by route and booking method. Pay at booking for lowest rates.
Tips for Trouble-Free Travel
- Measure at home - Check your bag's dimensions with a tape measure before traveling
- Use a sizer - Many airports have bag sizers near check-in; test before the gate
- Soft bags are forgiving - A slightly oversized soft bag may compress into a sizer
- Book early for overhead space - Later boarding groups often find full bins
- Consider credit card perks - Many travel credit cards offer free checked bags on specific airlines
