I'm not sure I understand correctly. If I buy BRU-BKK in Flex+ and BKK-BRU in Saver, I can't change BRU-BKK later if a Saver becomes available??
Downgrade is not permitted thats the problem. Only thing would be to cancel the ticket and buy a new one however ticket is non refundable because of the Saver/O class.
