Pros: Not much turbulent. Smooth.
Cons: I did not get the meal of my choice, also as I tried to check in at home, the system did not give me much choices to respond to, instead the system blocked me entirely from early check in and it wasn't enough time to make calls. I think check in should be made available at least 48-72hrs ahead not just 24hrs. Also walking from terminal to terminal in Frankfurt is way too far, it seems about 2miles + of walk.
