found it for 2000 CAD, Thunder Bay to Hamburg with 2 stopovers, 29 July- 4th August

Sorry, my flight across would depart from Toronto.

From Thunder Bay. I've been flying lots for work in the USA, but I drive across the border and fly out of Minneapolis to save $$. Even still, the cheapest flight I had was $200. (MSP to St. Louis)

from where, Toronto?

$2300 for me to fly to Hamburg :-(

it's hard to find the motivation to add a 4th festival to the list, I did go to Resurrection last year which was cool (and absolutely stunning location and people) but can't do it every year

When I raced in Italy my flight was only $1200, but that was in 2021 with Covid still lingering. It was sweet, I had an entire row to myself on the way back.
