flying from UK you have a few choices:
- direct flights on BA, Virgin Atlantic and Cathay Pacific from Heathrow
- indirect (e.g one change) with Lufthansa, KLM, Emirates, Swiss, Air France, Singapore Airlines, Malaysia Airlines
the second options will be cheaper probably, and give you departures fom regional airports in UK (ie change plane at their hub enroute) but you didnt specify where you are travelling from. they will take longer of course.
best option if you are a student.. STA travel or Trailfinders. they are agencie in the UK which focus on long haul from UK. otherwise go check options on
www.travelocity.co.uk
now for my personal choice - go for Virgin. the best entertainment system in the sky at the moment.
