I'm sorry for your loss, but I wish if you had posted this a bit earlier, this is for no benefit to me, but I just have friends where they can help, as every airline has reserve seats for such circumstances and emergency cases.
Anyways, please let me know if you want better arrangements for your trip back here, but let me know the carrier and the ticket class by PM.
Sorry again for your loss and to be honest, I'm afraid of the same, I feel like I've abandoned my family by moving here.
