A quote from the section called "destinations" on the Now Airlines web site:
Destinations
Final Destinations - Coming Soon
We are in the final stages of formalising our route network and will release a complete schedule when the booking system is launched.
The flashing destinations on the main web site page are for reference only. I am sure no one will want to go to Ibiza in the winter, so that is why they are announcing the actual destinations at the launch mid-September.
The launch of Now has certainly got to be the biggest launch of a new carrier since Go. One can only wish that easyJet stay away and let Now get on with their superior service they plan to offer. easyJet is ASDA in the airline market, Now is Fortnum and Mason.
