Oh it was so bad yesterday, even when it was sorted I still felt like ** the rest of the day. Yes, I don't get why the Thursday flight is more expensive, there were way more options available then on the Wednesday flight! So we are sitting together on both flights. I e-mailed the airline because I found out the luggage rule changed January 16th and tickets booked before that should still have the same rule. I just want that in writing from them

So if I get that, the luggage shouldn't be a problem anymore either.
I send the company a lengthy e-mail pointing out where they could improve their costumer service and how they could have prevented loosing two customers. (And I pointed out some bugs in their software I uncovered while on the phone with them) I had my fiance proof read the e-mail, he's always about staying nice and friendly and he didn't suggest any changes. I doubt I'll ever hear back about it, but I'm pretty sure they lost money on our booking (because they already approved the change with the airline), this way, at least they might be able to get something for that money.
EDIT: btw, I think the only reason it got sorted in the end was because I had already called them 4 times before they accepted the change by the airline. I pointed out that they never should have accepted it after 4 calls. I'm just so happy I spotted the change when I did, I guess otherwise I would have gotten the email about the change yesterday and they would never have changed us back if I hadn't called before.
