HUY's size vis-a-vis EXT noted, albeit EXT will grow substantially next year with the arrival of Flybe's low cost operation setting up there.
Off topic, but the list of IT destinations from HUY shows that certain destinations must be more popular from some parts of the country than from others.
I note HUY has two flights to Bourgas and one to Varna each week. My local airport at BRS, which is heading for 4 million pax this year and over a hundred weekly IT flights, can only provide enough pax to Bulgaria for one weekly flight to Bourgas, and even that only runs from late July to early September.
There is in fact a weekly AMM flight scheduled to Varna next summer, but Bulgaria still forms a relatively small percentage of the west country IT market compared to other areas of the UK.
