I need to know the answer to this question ASAP insha Allah if any one can help me out.

A girl is travelling by plane with the purpose of attending a Darul Uloom in which she will be boarding in insha Allah.The journey is an hour long.Is it allowed for her Mahram to leave her at the airport and let her travel alone,while another Mahram will pick her up at her destination an hour later.

Jazakallah
