Key Differences: International vs. US Airlines
Weight Limits
Most US airlines don't enforce carry-on weight limits. International carriers, especially Asian airlines, commonly enforce strict 7-10 kg limits. Budget carriers in Europe frequently weigh bags at the gate. Pack light or pay overweight fees.
Personal Items
US airlines typically allow a personal item plus carry-on. Many international carriers allow only one piece total, or count personal items toward weight limits. Check policies carefully.
Dimension Enforcement
European budget carriers are notorious for strictly enforcing bag dimensions. They may use sizers at the gate and charge substantial fees for non-compliant bags. When flying budget carriers, use bags that easily fit their specific dimensions.
International Checked Bag Considerations
Weight Limits
Many international flights limit checked bags to 23 kg (50 lbs), compared to some US domestic allowances of 25 kg. Some routes, especially to developing countries, may have lower limits. Overweight fees internationally can be steep.
Piece vs. Weight System
US and transatlantic flights typically use a "piece system" (number of bags). Some international routes, especially within Asia and Africa, use a "weight system" (total kg regardless of pieces). Know which system applies.
Tips for International Travel
- Pack a luggage scale - Weigh bags before departure and before returning home
- Use compression bags - Keep volume down while staying under weight limits
- Wear heavy items - Boots, coats, and heavy clothing on your person don't count
- Check each flight segment - Connecting flights may have different limits
- Book baggage in advance - Pre-paid baggage is often cheaper than airport prices
- Consider travel insurance - Covers lost luggage and delayed bag expenses
