Thanks, everybody. Ontheweb, I think you're right. DIL was able to get seats on Delta, but had no option to upgrade, and although ticket says Delta, because Atlanta to Barcelona is on KLM, couldn't get seats. That was on the weekend, but I called KLM for them this morning and was finally able to get through and got them two seats together, one of them an aisle. So that was great. But no other changes were available.
