I have a couple of tickets in which the flights were canceled by the carriers in the last few months.

One was a TAP ticket within Portugal. I actually had two tickets, got a credit for one but the other one, I've not gotten replies online and I've tried calling and can never get through.

The other was with Air Corsica. They have an online submission process and I can log in and see it but I submitted for either credit or refund back in early May.

Would Chase refund my CSR account for these, both flights with foreign carriers, intra-Europe flights, unresponsive carriers, canceled flights by the carriers?
