Ok, so I assume no one has flown this route yet. Reb Moshe, you?
(I btw booked 3 F awards for the end of this week on the 744 EWR-FRA route.
(Side note: I flew this route in F a couple of weeks ago, and the co-pilot was living in Israel, he later connected as a passenger on our TLV flight going home. I was in F he was in C, and the FA told me becuase they pay 10% approx for tickets booked, so they buy what is cheaper).
They usually have Flynet on board and UMA works fine on T-mobile, so I can talk and surf @35K').
