I think people understand them but don't agree with them. Price advertised should be the price you pay at the till. It's criminal that they get to say "sorry, we've changed the price of that whilst you were jumping through the hoops of navigating pages upon pages of add-ons."Looks like a lot of posters don't understand the airline's dynamic pricing models. Of course prices will rise at payment stage if more seats are sold in the time between you searching for them and trying to confirm payment. The price shown is only valid at point of search request.
We managed to get BA on Vueling from LGW for just over 200 each.
P.S. sorry for the weird homophobic abuse aimed at you later on in this thread - utterly bizarre and quite hard to understand.
