As an fyi whenever originating or landing in a US airport they must also follow US regulations. Got a full refund from VA for March 2020 cancelled flights- first waited like 120 days or something then ran out of patience. They were trying to give me vouchers (permissible under EU regs) but US requires cash option. I pointed this out to them and they got all cheeky and so I prepped a US FAA complaint form and sent it to VA’s corporate office (along with the text of the regulation they were violating and penalties, as well as screenshots of all the customer service texts etc) asking how they’d prefer to handle it. Full refund 48 hours later.
