Hmmm, Saudia have pushed my CGK-TUN return back by one day. Not really great as I had booked 2 nights in TUN hoping to visit town a bit.
Last time they did something like this I called the LDN office and got rebooked on QR fairly hassle free. It was last year and it was also booked via GTG. I think I read on some thread around here that they are stricter now than they used to be if you booked ticket via OTA?
Alternatively will they pay the extra hotel night in CJK? Not that it would be my top choice tbh. I love my 6 hour layovers in JED as much as anyone here, but would not say no to a shorter layover at Al Mourjan!
