Carry-On Only Packing List to Avoid Bag Fees (US/UK)

Carry-on only travel is the fastest way to cut baggage fees and reduce airport stress. It keeps you flexible on US and UK routes, especially when low-cost carriers charge for every extra item. This list focuses on essentials that work for 5 to 10 day trips without overpacking.

Carry-on size rules to check before you pack

Always confirm the airline’s exact dimensions for cabin bags and personal items. US and UK carriers vary, and budget airlines often charge if you exceed the size by even a few centimeters. Aim for a bag that fits strict limits and weighs under 8 to 10 kg when full.

Core clothing formula that works for a week

• 2 bottoms: one jeans or pants, one lightweight option
• 4 tops: mix of tees and one nicer layer
• 1 outer layer: light jacket or packable shell
• 1 comfortable walking shoe + 1 versatile second shoe
• 7 days of essentials: socks, underwear, and a sleep layer

Toiletries and electronics to keep it simple

• Travel-size liquids in a clear bag (under 100 ml each)
• Universal adapter and one fast charger
• Power bank under airline limits
• Document copies stored offline on your phone

Packing tactics that prevent fees and delays

Use packing cubes to compress bulk and group outfits. Wear your heaviest shoes and jacket on the plane to keep weight down. Keep liquids and electronics at the top so security is fast and you avoid delays.
