Award change to one segment => reprice => redeposit => risk losing other segments?
Have an award booked IST-LHR-DFW-SFO for later this month. Have talked to several agents and was told different things. I want to replace IST-LHR with XXX-LHR, where XXX is another TBD city in Europe. The award was booked under the old levels and I understand a reprice will be in order. However, it is unclear if this triggers a redeposit such that we will risk losing the LHR-DFW-SFO segments. Anyone have experience in this? In Europe now and this is my family's flight home, so need to be careful.
