Can you elaborate on the F experience on this route (EWR-CUN)? It is marketed under a fare as International Business Fare (E, or R) and so I'm thinking that is a fancy label for the traditional domestic F on an international route. Or is this a modified BF service without the BF seats?

Wife and I don't want to do Y on this trip (vacation) but if it is domestic F service may not be worth paying for the UG with double miles.

Thoughts?
