When is a sandwich not a sandwich? When the International Air Transport Association (IATA) says it isn’t. Or such was the case in 1958 when premium sandwiches served in the newly created economy cabins of several European airlines, such as the Scandinavian Air System (SAS) and Swissair, did not cut the regulatory mustard according to North American competitors like Pan American (Pan Am) and Trans World Airlines (TWA). To go to battle over a lowly sandwich appears quaint in 2024, especially when flying domestic where little is free. But international economy was just finding its footing in the late 1950s when IATA was hell bent on making the experience as miserable as possible. Besides, there is nothing lowly about a Danish smørrebrød.
