Same Day Change with Different Connecting City?
I'm booked LAS>LAX>GRU on 10.25, but see the 777 equipment on the LAX>GRU sector is outdated configuration.
Alternatives are to connect via MIA or DFW, but currently subject to a $300 change fee.
Is it possible to do a same day change for $75 including switching out the connecting city? Reading prior threads sounds like no online, but agents may be more accommodating.
Any advise or experience appreciated.
