Same same but different? (rerouted but unchanged flights)
I made a TP/TG award booking in May. Since October the booking has been carrying a note saying "*M*INVOL REROUTE AS PER IATA 735D" even though the flights are still exactly the same as they were when I booked. Absolutely no change: same flight numbers, same operating carrier, same departure and arrival times. Do I need to be concerned? Why would a ticket be amended even though nothing has changed?
