A mere £5 may get you an airline ticket from London to Hong Kong, if your luck and cheek hold out.Lufthansa is holding its second Internet auction today and tomorrow, selling off seats from British airports to venues as near as Barcelona and as far as Singapore for a fraction of their normal price.The last time the company held an auction, in February, there were more than 5,000 bidders and bargains included a return ticket from Manchester to Hong Kong for £77, a return ticket from London to Toronto for £102 and two business class tickets from London to Boston for just £375. To get involved in the 48-hour auction, you will need access to a computer and to the Internet. You then call up Lufthansa's website at www.lufthansa.co.uk and make a bid for any of the flights available, which are from London to Singapore, Geneva, Warsaw, Venice, Bologna, Munich or Frankfurt; from Manchester to Hong Kong, Vienna or Singapore; and from Birmingham to Vienna, Barcelona, Venice, or Munich. There is an average of two pairs of tickets available on all routes. All flights are routed through either Frankfurt or Munich and departure dates are from one to two months away. The minimum bid for any of the flights is £5 and you can make as many bids for as many flights as you want. Remember this is an auction, so an opening bid of £5 is unlikely to secure a seat.Once the auction closes tomorrow night, the highest bidder for each flight will receive an e-mail from Lufthansa inviting him or her to send back their credit card details within 24 hours.
