Most probably but the timings of those flights have never been convenient for travel to London particularly for business. The first morning flight off the island is not until 09.55 or 10.25 and Gatwick is a much longer journey into the centre than London City. The evening flight off the island is even worse and with frequent delays it does not get back to Gatwick until circa 11.00pm.
Easyjet only use the island as a 'filler' and so put the flights on at less than optimal times and their policy to fares when Flybe went into administration resulting in charges of up to £500 return to Liverpool demonstrates how they operate!
In my opinion they are in no way the answer for serving the centre of London and providing a regular well timed service to and from London for the island.
