United is having a huge sale on flights to Miami, Phoenix, Dallas, Philadelphia and Charlotte USA. These are the cheapest flights we have ever seen to mainland USA. Lots of travel dates from Apr - Nov/20.

With United Airlines, for example, all bookings made between 3-31 March 2020 can be changed for free over the next 12 months – regardless of the destination or travel date.
