Condor partnership has been around for a few months now, but having just returned on a Condor redemption thought I'd add my brief experience.
Flew a reward YVR-FRA return for 25k each way. OLCI for the flight to FRA wouldn't process (for me) and had to check-in and have seat assigned at the check in counter at YVR. Had the option of calling in ahead and paying $50 for a seat but figured I'd chance it and just hope for an aisle at check in (I got one). Flight to FRA was uneventful and left on time, which seems like a rarity with Condor flights. I sat in 29H on the outbound, not a ton of legroom but having the aisle to extend your leg definitely helps. The hot meal served was very basic, just pasta with some tomato sauce dumped on top along with a cold potato salad-type side, a bun, and a desert. I think they did drink service 3-4 times on the flight. There was also a small meal about 2hrs out of FRA. IFE had 1 free movie and 1 free TV show, unless you bought an entertainment code for 8 euro onboard. I had numerous movies downloaded on Netflix, so didn't bother. Arrived at remote stand in FRA and had to be bussed through to customs and baggage claim.
Flew in the window seat 29K on the return FRA-YVR, didn't have the option to change my seat but at least OLCI worked when departing FRA and was able to print BP using the self service counters. The return flight was delayed by an hour due to late inbound from ANC. I had checked flightradar earlier and it was showing a different aircraft would be operating our flight that had been on the ground overnight, so I was surprised when the delay was posted, but I guess Condor can shift their fleet around on a whim at FRA. Bus gates for loading again, and we stood on the bus next to the aircraft for 15 minutes while cleaning staff finished onboard. Got onboard and ended up sitting around for another hour so maintenance could fix a broken overhead bin. When we finally got airborne we were about 2.5 hours late. Hot meal served on this flight was pasta again, but this time the sauce seemed creamier (and better) and there was also some cheesed mixed in. Came with the potato salad, piece of cheese, a bun, and a desert. Second meal served prior to landing was the potato salad again and 2 cold sausages with mustard, along with a pretzel pastry type thing. Landed in YVR about 2 hours late and luckily no bus gate, but the bags did take a while to arrive.
Overall, Condor is certainly a budget airline and you can notice it during your flight (at least in economy). Flights are regularly delayed, legroom tight, and IFE isn't free, but if you're looking for a cheap redemption to Europe I'd certainly fly them again. Just thought I'd add my voice to the other posts here in case anyone was thinking of booking an economy redemption with them!
