I don't agree.
I'm not trying to book 6G or BA through Expedia. I'm trying to book directly with 6G. The fact that it might be hosted by someone else is immaterial - I am trying to book a 6G service. I don't care how it's done, it's them I have the experience with. If I want a tin of Heinz beans, I don't care how Tesco gets it to the supermarket, as long as it's on the shelf when I get there. If they have run out, then I'm disappointed as I like Heinz. If I was after any old can of beans, then it wouldn't matter if they had own brand. Now compare this to flying. I want the equivalent of Heinz beans - same day booking. If I can't get it, then I am disappointed. If I just want to fly - the own brand beans - then it doesn't matter how I book, as long as I get to fly, but I'm disappointed as I want my Heinz beans - to book on the internet today for a flight later on.
As a flyer, I have seen other airlines provide a same day booking service, or for a flight departing in less than 24 hours. bmibaby is one example, and it's parent is another. Therefore I expect this from all airlines now - therefore I'd write the same thing about any airline, it's only that this thread relates to 6G that they are being criticised. If I don't get it, then I might chose to fly with someone who can offer me more convenience or what I like to call a better package. ie good flight times, punctuality, ease of booking etc.
The fact that I will probably chose to fly 6G home tonite is because I want to get home tonite not spend another night in a hotel waiting for the baby flight tomorrow. In a similar light, it's because 6G have offered a better package (ie to get me to Belfast in the morning rather than lunchtime) that I have opted for them in the past as opposed to baby.
We - as in the public as well as flyers - have been spoilt by the internet. We know what is possible so we now demand it from all companies. If we don't get what we want, we may decide to go for another option, but are disappointed with our first choice let's us down.
