Pros: "I paid 60 bucks for an emergency row exit, take get some extra leg room and space so that I would be fresh when I arrived in Munich. However KLM allowed a passenger — who did not pay for the emergency row to sit next to me because he needed the extra space because he was a liarge man, and clearly didn’t fit very well in the economy seats. Thus I I lost all the extra space and actually would of preferred a regular economy seat. that would’ve been more preferential then paying $60 and getting less space than I would’ve had it in a regular economy. I understand the other passengers comfort was important and if that was the case he should’ve paid $60 as well."

Cons: "I booked KLM flights (Cork - Tampa return) but the planes were in fact Aer Lingus and Delta. So I have no idea what KLM is like. When I checked in at Cork the ground staff could only give me a boarding card for the first flight. For the second one she said I would have to go to the Delta counter in Amsterdam. It was difficult to find a counter there or staff as check-in was all by computer. The computer kept saying 'error' when I put in my code. I eventually was directed to a KLM desk (nicely hidden). I was told that my seat no longer existed. At this point the flight was ready to board. Thankfully the KLM ground staff were extremely helpful and reassuring and upgraded my ticket to economy comfort. On the way back, I could only get a boarding card for my first flight. The second two I had to collect at the boarding gate of the second flight."
