What are your BEST/WORST experiences in some of the Airline Companies?

That is a shame because having flown in and out of Singapore's Airport I would say it is one of the best airports in the world. However the airlines vary considerably and it is terrible to be stressed when traveling in a plane. I flew to the USA and they saw I had a one way ticket so were happy when I showed them my onward ticket because I was flying around the world. My worst flight was from London to Sfax via Tunis. It was very bumpy in the air and I had coffee spilled all over me. I suffered sickness on landing and terrible ear pain. The cabin crew were not very friendly. My best flight was when I got a free upgrade from Male to London. It was a ten hour flight from the Maldives and it was incredibly comfortable. Service was excellent and so different from economy class. Other fantastic flights I have had because of the views like the pyramids, the reef, the islands and Sydney Harbor. Good luck with future flights.
