I recently flew Condor from Prague to Vancouver, and it was quite the experience! The boarding process was chaotic, as everyone was instructed to board buses regardless of their groups, which led to some confusion. We ended up waiting an additional 30 minutes for a few missing individuals, but thankfully, we still made it on time. Once aboard, the planes were consistently hot, which made for a bit of discomfort. However, the silver lining was the delicious food that made the journey much more enjoyable. The staff were incredibly friendly and patient, which added a nice touch to the overall experience. Despite the hiccups, it was a good trip overall!
