Yeah, rescheduled, but you don't get the nice low fare if the price has gone up. This, from the United web site:Most of the airlines are offering one free change with these low fares. So if the island is still closed, the tickets can be rescheduled for a later date. As mentioned earlier, if you're booking a resort or other accommodations, be sure those have that option as well.
Late July is still possible. Gotta stay optimistic!
Tickets: For tickets issued March 3 through April 30, 2020, customers will be permitted to change free of charge to a flight of equal or lesser value for travel up to 12 months from the original ticket issue date. If the new flight is priced higher, the customer may change for no fee but must pay the fare difference. If the new flight is priced lower, the customer may change for free but no residual value will be given. If the customer decides to cancel their flight, they can retain the value of the ticket to be applied to a new ticket without fee for travel up to 12 months from the original ticket issue date.
