Zmanim while flying.

[Yaakov Ehrenkranz]

I am going to Israel tonight (Tuesday night) and was wondering about the following:  Attached is Zmanim for the flight from myzmanims nifty new inflight zmanim feature. If u look at it, and I imagine this is somewhat typical of jfk-tlv night flights, it seems that the only time to daven is in the middle of the night- like between 2:30-5:30 ny time- exactly when you'd want to be sleeping. Does Halacha expect someone to stay up/ wake up to do that or is there some other way of looking at this?

Any help appreciated... A little last minute, I know. But any concrete ideas, ideally if based on sources, discussions with poskim etc would be awesome. Thanks! 

Yaakov
