My flight to Europe was cancelled and rebooked. Bags got lost by FinnAir. Flight back home from Europe was cancelled the very next day after we landed. Zero compensation for these back to back cancellations on the exact same trip. Kayak doesn’t help with flight cancellation before trips says to contact trip protection only for trip protection to say it’s up to kayak. Don’t fly FinnAir.
