The best way to travel from the UK to Kassel in Germany?

Answer 1

Easyjet or Ryan air are cheapest and most reliable from either Luton or Stansted. With Easyjet you can fly via Dortmund, Cologne or Hamburg and with Ryanair via Dusseldorf, Frankfurt or Hamburg. But you need to check these airlines websites for full information on seat availability and fares on date you want to do the trip and it also depends from where in the U.K you want to fly.
