Washington to London for $499 roundtrip in business class??! It’s true. If you can leave Washington-Dulles on May 6, and return from London-Stansted May 7, 8, or 10, all-business class Maxjet will take you. Apparently valid on these dates only. I just checked, and seats ARE available. Go to the Maxjet homepage, and be sure to enter the promotional code “MADMAX” before clicking “next.” But hurry, these fares are likely to sell out faster than you can say “Independence Air.”
