I'm glad I saw this; I was routed to fly tonight the last DFW-DEN-PDX flights of the night. I had a bad feeling I might never leave DFW, and getting stuck in DEN tonight would have been a mess. I am getting rerouted via LAX, arriving almost midnight. Unfortunately it's CR700s the whole way (one upgraded, the other waitlisted), but getting home for meetings trumps aircraft right now. I'm glad I check FT this morning as I had no idea whatsoever about this. Let's just hope I don't wind up with a worse problem on the new itin for some reason!
