For laid-back flying, nothing can beat Albatross by Fleetwood Mac, or "Shine on you crazy diamond" (first 5 minutes of wish you were here), by Pink Floyd. Almost up there is "Echoes" from the album Meddle - again by the Floyd.
There's a lovely track by Brian Eno called "Ascent" on the Apollo album that's appropriate for smooth flying.
For spirited flying, I think that "Dance of the Furies" from Orpheus & Eurydice by Gluck is brilliant! And for tongue-in-cheek pomp, the "Luftwaffe March" from the Battle of Britain by Ron Goodwin is excellent.
Other suggestions would be stuff by Vangelis - like the theme from Blade Runner, or tracks from Albedo 0.39.
And I have to include the Sinfonia from Cantata #29 by
JS Bach, because it is my favourite piece of music to drive to - and I just wish I could fly with it also!
NB - All are without lyrics (the Floyd tracks start with at least 3-5 minutes without lyrics).

ps - if you want to take the p155, try the Flower Duet from Lakme by Delibes
