Just an FYI for those who requested a refund - I submitted my request on the first day I could and received a Pay Pal confirmation of the refund back to my credit card this afternoon. Took a while, but it’s one more thing I can scratch off my list for our cancelled DL vacation later this month.
Now I just need the Canadian government to extend the US border closure past the current expiry date of the 21st, so I can call my airline to cancel our flight on the 22nd.
