Condor delayed my flight two full days. Can I expect to receive a refund or future travel voucher?

Call and ask them for a full refund. This is a totally different itinerary than the original. If I was in your place, I would not assume that this trip will go forward in general, so I would aim for getting my money back.

The regulations can be found here: https://europa.eu/youreurope/citizens/travel/passenger-rights/air/index_en.htm

I'm not a legal expert, but in your case I think you are entitled to a refund.

I just received an email from Condor rescheduling and postponing our flight from Seattle to Frankfurt by two full days … from October 1st (arriving the 2nd) to October 3rd (arriving the 4th).... Condor’s email is very polite,

They are playing games. You are entitled to a full refund. The process sucks but call em up and get your money back.

How long do I have to redeem my voucher?
Until 30th June 2022
What happens if I do not redeem my flight credit?
The value of the flight credit can be paid out from 1 January 2022.

Depending on when and what sort of ticket you have, you may be able to get a refund beginning Jan 2022, if you have not used the voucher by then. ( assumes they are still in business)

Thanks to all for your replies. I will let you know how it turns out.

Condor cancelled our May flight completely and sent us a voucher. We contacted them and said due to our age (and the virus) we might not be traveling next year! It took awhile, (two months), but they cancelled our voucher and put the $$ back in our bank account. A different situation, but they did honor our request. I think you should have no trouble.

Why not call and ask if there is an alternative flight that might suit you - one flying earlier, for example?
Regardless of the airline, whenever they change my flight to something I don't like, I immediately get onto their website and look at options that I will accept. (don't look at prices, just dates and times). I then call and say the change won't work for us. Offer the date and route you would accept and see if they will rebook to that one.
Now, occasionally, it means I have to leave ahead of plan, and that means an extra hotel cost or such, but sometimes that's the lesser or waiting for a refund, and not being able to rebook on an alternate airline at a much higher price. Consider it as added adventure days.

Good news! I called the Condor 866 service number yesterday afternoon and they agreed without argument to cancel and refund the full amount of our flight. The funds will be returned to our credit card within 15 business days. They were very understanding … I suspect they are getting lots of my kind of calls. Resolving this situation is an example of why I try to book through the airline itself, rather than through a booking agency.
