From: "Bill Hough" <psa188@xxxxxxxx> Sent: Tuesday, January 18, 2005 9:39 AM <snip> You sometimes find big price differentials for exactly the same flights, depending on which airline supposedly sells you the ticket. The reason is "code-sharing," a practice in which airlines put their brand, flight number and prices on flights actually operated by some other airline. With the growth of multi-line alliances, code-sharing is getting more prevalent all the time. The net result is that you now have to check more different lines than ever to make sure you're getting the best deal. I say: I and my children are flying to western Ireland in March. The flight sold by Aer Lingus in their A330 is around $750 RT (the price changed upward while we were trying to choose) when the same seats bought from AA were near $2000. BA would knock another hundred off the Aei Lingus price if we flew to Heathrow on BA and back to Shannon on Aer Lingus, spending another 4 hours early in the morning to do it. We're coming back through Dublin to save some money, but the time we give up is in the afternoon. )8^(( Gerry http://www.pbase.com/gfoley9999/ http://foley.ultinet.net/~gerry/aerial/aerial.html http://home.columbus.rr.com/gfoley http://www.fortunecity.com/victorian/pollock/263/egypt/egypt.html
