So, we're scheduled to fly ORD to LHR, with one connection each way, departing July 21, returning August 13. Booked through Virgin Atlantic, with codeshares on Delta for three of the four legs. Yesterday I got this message from VA: "We are writing to let you know that there have been changes to your booking. Due to the current situation with COVID-19 we have significantly reduced our flying programme and need your help in getting you rebooked. Please be aware we have options to keep your ticket open which are subject to terms and conditions." And then they tell me to call. They have not automatically rebooked us on alternate flights. Does this count as a cancelation and entitle us to a refund? Or, if I call and they tell me there are flights available that are on different routes but that would get us there about three hours later than planned, does that mean we're out of luck and stuck with the voucher? Secondary question: if we end up stuck with a voucher, could we request to have it come from Delta, since I worry that VA won't be around by next year given their financial troubles? Thanks in advance!
