Just as an FYI, I had booked a package trip through Expedia to Greece for May 19.
I had to be patient to get through, but they are refunding my United flights. The hotel in Athens (Athens gate) I booked non refundable....but they are issuing me a voucher good for 18 months. If not used within this time, they will refund.
Also through Expedia I booked separately a hotel in Naxos (hotel Galini). This was non refundable...but they gave a full refund (already back on card).
Lastly, booked a hotel on Santorini, also doing the 18 month voucher.
All in all, a very positive outcome, and I look forward to getting to Greece one day soon!
This was wording in regards to Hotel voucher:
Faced with the unprecedented turn of events, the Greek state, as well as other EU countries, recently passed a law that allows businesses in the travel industry to issue a voucher instead of extending an immediate refund.
If you do not redeem your voucher within 18 months from the issue date, the entire amount will be returned to you at that time.
We assure you that we will show you flexibility, honoring your booking at any time over the next 18 months.
We thank you for your understanding and support, and very much look forward to giving you the warmest of welcomes in Greece when you are ready to travel.
We wish you health and optimism, and always remain at your disposal for any additional clarification you may require.
