Having had the profound misfortune to be obliged to visit Southend of late,I can only suggest that east european routes would be very profitable since the surrounding area seems to be overun by their offspring and type,assuming of course they exhibit a desire to leave the area,which I very much doubt thanks to our biased benefits system
Seems to be the same in most areas these days. I have no doubt that if Southend got a few Eastern European routes there would be a new influx of immigrants to the town. Luton is over run now with Eastern Europeans who could just afford the air fare to England but not the rail or bus fare to leave the town.
I have seen on many a morning Romanian Gypsies complete with headscarves and large gold hooped earrings pulling suitcases down the airport’s approach road as they head for the town.
