Hi Chinook
I don't think that it is "asking for a discount" it is about airlines exploiting people. It all comes down to "supply and demand" If the airlines think that there is more demand for a certain flight, they nearly always bump up the prices!
School holidays are a prime example. Why should a flight be more expensive during school holidays? The operating costs are exactly the same as any other time of the year.
The fiasco last year with the "Ash cloud" was also a good example. The same when other operators went belly up, prices suddenly shot up, why? because they know they have us over a barrel.
Yes, I can understand that airlines operate a business and want to make a profit but surely, prices should remain at a constant level.
