Why did they change it?
The old site was not perfect, but most of us were used to it and it generally worked. In reading a number of pages here I see the only positive comment is that some think it looks more modern . That's very subjective st best and hardly offsets the amazing number of deficiencies many have clearly identified. For me it no longer is intuitive at all, takes more steps and is much slower - probably due to all the useless pictures we are now subjected to. When I visit other airline websites the feel is usually to some degree intuitive. Not here.
