Apparently, although I have yet to have the figures confirmed, there has been an increase this year of a million Pax on last year. The terminal is too small especially on days there are US flights made even worse of course with the additional security restrictions.
If you can take a look from airside however you will see quite extensive building work going on to increase the size of the building, we are told there is even more to come, lets hope it does increase the departure lounge size.
