Thinking of using Continental metal instead of KLM on several upcoming transatlantic Y trips to IAH.

Does anyone have any suggestions as to whether the AM flight or the PM flight is beter?

They are both 767's (i think) so I assume seating arrangements would be the same.

In Y class one has to shuck out 5 USD per mini-wine, but are there other considerations that would lead me to stick with KLM?

As FB Gold Elite Plus would I also have access to priority/select seating and such?

any suggestions would be great...thanx
