Obviously, I understand that aircraft types can change at any point including up to/right before boarding (or after boarding if you get really unlucky). I have the option to fly direct from Chicago to London this August but decided to do a connection via DFW to fly on an A380 (WTP). I was wondering if people had opinions on the likelihood of an aircraft swap between now and then? I think if I end up on a 777 I'll kick myself for not just doing that direct from Chicago!
