Have revenue tickets booked TLV-EWR and the United site is really helpful with easily changing flights, many times for free if the fare class has availability.
I can only change the first leg to any date until the date of the return leg. However, i can change the return leg to anytime in the future. So would they allow me to change the return to say 4 months later and then I'd be able to change my first leg to anytime before that new return flight?
