Hi, can anyone please offer some advice.
Very early on Sunday morning (00:22 on Sunday 29th October 2023) I am flying from Stansted to Istanbul SAW. I just tried to check in online and it says "Online check-in is not available for this flight"

Am I doing something wrong or is that normal for that particular flight with Pegasus?

Thanks for any help and best wishes

For clarity I don't think this is a case of me trying to check in too soon. ?
