The character name Sebastian Flight is a reference to Sebastian Flyte played by Anthony Andrews in Retour au château (1981).
The "Trident" aircraft used for exterior shots in the series was an ex-British Airways aircraft which suffered a heavy landing at Glasgow Prestwick International airport. It was found to be beyond economical repair to re-enter flight and became a training tool at the airport for tug-drivers and firemen. It was re-painted in "Air Scotia" colors specifically for the show.
In the title sequence, Alan Cumming [Sebastian Flyte] does an incorrect dance move. Whereas the rest of the stewards leap with their arms up, Cumming performs a move which is a throwback to his days in Cabaret in London's West End - a Nazi salute with two fingers of his other hand forming a 'moustache'.
