Apple Vacations have previously only wet-leased their A320s during the peak season from UK airlines such as Airworld and JMC. From now on, they will operate most of their flights on USA 3000.
They already have a webite that's been up and running for a couple of months now.
The name USA 3000 was chosen because Apple Vacations have a small shareholding in Canada 3000, hence the similar name. AFAIK there will be no operational links between USA 3000 and Canada 3000, and they will have completely separate liveries.
