I have a sister who is a Philippines overseas worker in Oman. She is going home tomorrow for vacation. She was previously advised that her passport will not arrive until next week, that she can still use her old passport. They even gave her a validity extension of up to one year so she can use it for tomorrow's flight, and for her return flight afterwards.
However, just yesterday, she received a message from our consular office in Oman saying her passport has arrived for pick-up. The office will not be open until Sunday, since it is weekend there now.
Can she still use her old passport, or will it be deactivated since the new passport arrived even if she hasn't claimed it. Is it really necessary to cancel the flights and get the passport on Sunday?
