Welcome to FT

If AC gave it to FedEx or when they do... ask for a tracking number so that you can confirm when it was shipped and when it will arrive.

In the meantime if you need essential items buy them and keep the receipt to make a claim with AC. Or if you purchased your ticket with a credit card check to see if they have baggage insurance, most premium cards do. You might qualify for some compensation there as-well.

Good Luck
