Love flying!! I'm so silly about it that I live under the local flightpath near the runway and my main criteria for what flight to get is to go on an airline or aircraft I havn't been on before... although OneWorld FF membership has curtailed my ways a bit...
Off the top of my head I've flown with: American, British, Aer Lingus, Ansett, Air North, Malaysian, Piedmont, Qantas, Garuda, Skywest, Thai Orient, Merpati (Indo), Cathay Pacific, Air NZ and flown on various models of 707, 717, 727, 737, 747, 767, 777; A300, A330, A320, Embraer RJ and Brasilia, F27, F28, F50, Bae 146, DC-9, DC-10, L1011 plus various light aircraft and a 'Mash chopper'. I flew 100,000 miles Sept 2001 -Sep 2003 but haven't flown since! Planning an RTW flight next year on FF points!!
Scariest was on a Garuda A330 which changed sound mid-flight and was withdrawn from service on landing... My worst airport - Delhi for general awfulness. Favorite coach class - American for the space. Favorite to fly on - 767 or DC-10, again for space. Best lounge I've been in - Delta in Frankfurt for the range of liquor and the quiet area with big leather recliners with personal headphone sets. BA do good lounges too. Worst toilet experience - BA London-Delhi - they were doing it on the floor!!!
What would I do if I won Lotto? Buy a small airline! My 10 year prediction? Airbus and Embraer will dominate leaving Boeing either kaput or as a much smaller player with just the 777 and 787.
