I am trying to book a one way flight from Copenhagen to Frankfurt and have had no luck with the larger well known carriers as they charge up to $85 for my checked bag. Needless to say, that short flight will cost over $200 which seems unreasonable for such a short distance. - Does anyone know of local carriers that I can check out? Last year I found a list of low cost european airlines on this site, but now I am not able to see that link anymore.
I would search on one of the big sites such as Kayak and Skyscanner. You can filter by ticket price and then look up an individual airline's policy on your own.
www.skyscanner.com specializes in one-way flights from the so-called budget airlines. It also covers the traditional lines. Most of the flights it lists for this route require a stop-over. Looking ahead a couple of months, $200 (US?) appears to be par for a direct flight. But it is impossible to accurately judge the cost without knowing your date of travel which can have a major effect on price.
A quick search for a random date next month gave me cheap fligths with SAS (Scandinavian Airlines). They don't charge for checked bags.
Just to update, I just booked a flight with Scandinavian Airlines (SAS) but learned an important lesson which I want to share. The lower fares advertised by most of the search engines (like Kayak or Skyscanner) are "SAS Go Light" fares, which charges $75 per bag. But that is not clear when booking, and in some cases they even say it is free (which is not the case). I ended up calling the airline for clarification and found out that the "SAS Go" fares which cost a little more do allow for a checked bag. - SAS also charges if you try to pick your own seat.
My husband and I will be in this situation on June 25th. I am deciding between taking the train or flying from Copenhagen to Frankfurt after our cruise. How was your experience with SAS in comfort, travel time, and price? We will have checked bags. Thank you.
