On my itinerary I am flying JFK-HKG, HKG-TPE, TPE-HKG, and HKG-JFK.
Now, I had assigned aisle seats on all of them. However, when I checked today I noticed the 3rd leg (TPE-HKG) the seat assignment is gone. Does this mean I got op-up or someone in DM decided that he really wants that seat and I got kick off of it...
