There is a long list of poskim that say it is assur to daven with a minyan on a plane. Someone even put out a sefer with all the teshuvos on this 1 question. Seems to me that when you come upstairs, they will have a bigger issue if you did daven with the minyan, than if you didn't.
I know that there are many people that haven't missed a minyan in x number of decades, and I'm extremely impressed with them, but as a jew the number 1 thing we have to do is what God wants us to do.
You can get a red-eye to London, and then the red eye to Israel, and you shouldn't have to daven on the plane
