Online Itinerary Change
I'm not sure if this common knowledge that you can make an itinerary change online? Well, I had Star Alliance award on Swiss and I notice there was a flight change on one segment and cancellation on the other segment. I did the online chat and they informed me to use the manage trip selection. I did, it gave me an alternative flights to choose from. I made the change and new seats are confirmed.
This a step in the right direction. However, I wasn't notified of the flight changes from Lifemiles. Thanks goodness I checked the status on CheckMyTrip and crossed reference with Swiss Air.
I hope this is helpful.
