Seat assignments show on lh.com but not swiss.com
Some time back I made an award booking through United on LX, SFO-MAD-SFO.
When I look at my record on lh.com, it shows seats assigned. But the same record on swiss.com shows no seats assigned, although attempting to select seats results in an error.
Should I be concerned at all, or rest assured that the assignments shown on lh.com are correct?
