In November, United Airlines announced it became "the first major U.S. airline to offer lie-flat beds in business class." A Washington-to-Frankfurt flight was the first to carry the new seats. Further proof of the airline's effort to boost premium services is the multi-course menu designed by famous Chicago chef Charlie Trotter. United is refurbishing 97 aircrafts with 180-degree, lie-flat seats. Delta said it plans to introduce lie-flat beds this year, and American is already adding more comfortable business seats to part of its international fleet.
