Scoot reschedules the timing of this flight (Athens to Singapore) a lot. We booked Scoot premium months ahead but few months in they decided to push the flight out by a day. To make things worse, they released out bulkhead Scoot premium seats which we had selected at purchase which we only found out by chance. When we realized that (still within the same day), we were left with only sub-par seats. So obviously after rescheduling, they allowed all passengers to re select seats on first come first serve basis. The call center was unapologetic. It's unacceptable
