I need help as following
I have a flight for mid Nov with united to Israel with 2 stopovers with the third flight being Lufthansa.
For certain reasons I'm gonna need to change my ticket twice ams three second one is gonna need to be to a united direct flight on april 13th erev pesach (first one doesn't matter as long as it's before the end of March).
Now I know that changing a flight with united costs 180$ before anything which means that it will cost me at least 360$ the question is what is the cheapest way to do this?
