I would be traveling from Mumbai - Doha - Cape Town South Africa. (Qatar Airways all the way) This would be in late June.
While the Mumbai - Doha is an easy and sweet ride. The next connection from Doha to Cape Town is 22 hours away (layover). It is probable that there are other flights which go from Doha to Cape Town (on Qatar Airways) within that 22 hour window and am sure there is possibility that there would be no-shows as such. In such a scenario is it possible to change the tickets for the earlier flight by paying some small difference ?
Is it possible to ask the check-in counter if such a possibility comes up. I am sure there are and would be empty seats and the airline would like to have 100% occupancy in the flight.
