Cons: "The flight was half empty and when I tried to move a row ahead of me (from economy to economy plus), the flight attendance rudely told me I had to move back to my seat since the economy plus seat was $70 more. However, a reasonable airline would upgrade their customers to first or economy plus to not only appease their customers but to fill some empty seats. Therefore, I had to spend the entirety of my redeye flights crammed next to someone while I was looking at an almost empty economy plus section. Also, we boarded earlier than expected but we spend an extra hour on the flight waiting to take off. I would not have minded boarding early if we had taken off early, but we took off an hour later."
