Carry-on size limits have not changed, but enforcement has, with automated sizers now flagging bags that passed by eye for years. What a gate check actually costs, the difference between voluntary and forced checking, and what has to come out of the bag before it goes to the hold.
There is no industry standard for the under-seat bag, and the variation between carriers is wider than most travellers expect. Airline by airline figures, why basic economy has made this the allowance that matters, what actually fits under a seat and how to buy a bag that never gets questioned.
Some terminals stay open all night, some close entirely after the last departure, and a few are genuinely comfortable. Where to find the seating that works, what to pack for a cold and brightly lit night, how to secure a bag while unconscious, and when the airline owes you a hotel instead.
Umbrellas clear US security without difficulty, yet golf umbrellas, pointed metal tips and loose full length models still cause problems at the gate. A look at what airlines count toward your allowance, when screening pulls an umbrella aside, and whether packing one is worth the space.
Leaving the airport on a layover comes down to two questions: whether you may legally enter, and whether the timing works. A country by country breakdown including China's expanded ten day transit scheme, the UK authorisation now required of US citizens, and why US connections are the hardest of all.
Thailand's two coasts run opposite wet seasons, so the month matters less than the region. A packing list built around heat, humidity and temple dress codes, what to buy there instead of carrying, the arrival card that catches people out and why laundry beats a bigger suitcase.
Power bank rules changed more in 2026 than in the previous decade. A breakdown of the watt hour limits, the new quantity caps and overhead bin ban, how to convert milliamp hours, why gate checked bags catch compliant travellers out, and which airlines go further than the international standard.
Airport security is relaxed about supplements, with no quantity limit on tablets and no requirement to keep original bottles. The complications sit elsewhere: the 12 ounce powder threshold, liquid vitamins under the 3-1-1 rule, and destination countries that regulate melatonin and high dose vitamins as medicines.
Being able to wash clothes on the road is what makes a small bag possible, since a traveller who does laundry carries one week's wardrobe for a month. Five methods compared by effort and cost, where each one actually exists, how to dry clothes overnight and which fabrics make all of it easier.
Border control has become the least predictable part of a journey, with European waits stretching to hours since the biometric Entry/Exit System rolled out. Realistic timings by region, what actually speeds you up, why US connections need far more buffer than the published minimum, and how to plan the gap.
