I think it's a possibility - loads are significantly up this year to the point that 2015 may only fall about 20,000 short of 2014 despite the loss of Ryanair flights to Prestwick, Kaunas, Gran Canaria and Eindhoven. Considering that loss of capacity the numbers have been quite impressive this year - August was the only major fall off compared to 2014.
In 2016 the existing routes plus Edinburgh, Birmingham, Reus, the increase in capacity to Manchester and the probable BA codeshare on Gatwick should more than make up the 20,000 and get the numbers back over 700,000 and ahead of 2014 total.
