It's not really the case now. They've got an extremely lame reservation change system. I've got to send them my request with the requested dates that I'd like to change my reservation to and they'll send me the total estimated cost in 48 hours. I already sent one request and I've got a reply that it'd cost me more than $3000 to change it (because there are only business class seats available on the dates I selected) - there isn't even an option to check +/-3 days dates... It'll take forever to find dates in the same class if I can only check one date every 48hrs...
