Condor Airlines Phone Support - Do they answer eventually?

Yes, they do eventually answer. I successfully cancelled a flight with them once. I waited on hold for a long time and eventually spoke to someone. It sounded like they were really in / from Germany based on her accent. She said their computer system was down(!) and she wouldn't be able to process my cancellation request while we were on the phone. But she would put it through and I'd get a confirmation eventually. I asked a lot of questions, sort of thinking that sounded like a scam. She seemed offended that I would think she wasn't going to do her job properly. And she did do it, my flight was cancelled within the 24 hour window after I booked and I didn't have to pay anything.

The best places to look are on the Condor website or at the small print of your ticket (Google "Condor Classic fare...and voila). All the fare rules are spelled out in both places. It looks like you're out of luck except for taxes and fees.

"Cancellation
In the case of cancellation or no-show, it is not possible to refund the airfare (except taxes & fees). Selecting our attractive ”Flex” option gives you more flexibility for rebookings and cancellations."

Thank you, Agnes. I'll try them again. $80 is $80.

If you manage to recoup anything, please post back.

I shall. I may also sue for emotional damages after hearing their hold music while in sleep paralysis last night.

It does look like you can 're-book' for a fee and fare difference if you are re-scheduling the trip.

Depending on your situation, you may want to explore that option when you penetrate the muzak maze

Good luck
