tripwhys is a library of plain answers for travelers. Every page takes one question people really ask, about flying, airports, hotels, cruises, rental cars, documents, insurance or safety, and answers it in plain words.
We are independent: we are not an airline, a hotel group, a cruise line, a rental company, a booking site, an insurer or a government agency.
Rules, fees and policies change. When a page touches on a rule, check it with the airline, hotel, cruise line or official source before you travel.
