Good morning!*A few months ago I bought a round trip through the Expedia site that included a flight to Berlin (TXL) from Frankfurt (FRA) with Lufthansa. **My Departure trip was on the **th of June, and the Return trip (TXL to FRA – Lufthansa **, at *:**am) is set for the **th of July, —so for tomorrow—, with Lufthansa too. **Through Expedia, a few days ago, I tried changing my TXL to FRA flight so that I can fly to Frankfurt from Salzburg, Austria instead (Lufthansa **** at *am). I have bought the flight ticket arriving at FRA at around the same time as the flight I originally had, but I can't see this new Salzburg flight replacing the Berlin flight on my itinerary on Expedia. This Salzburg flight to Frankfurt is also Lufthansa, through Austrian Airlines. **I was wondering if I had to contact this airline to make sure that the Berlin flight to Frankfurt that I was taking originally is going to be redeemed or replaced. What can I do in this situation?**Thank you very much!
