Well, I've been using both Glasgow & Edinburgh flights from Luton extensively over recent months, and certainly all the first 6 to 8 rows, i.e. Up Front Seats, have had a very high proportion of "suits" on board, but I can't really comment on other routes. Glasgow is only 2 per day mid-week in summer, other weekdays 3, although this does tend to increase over the winter period. The terminal is always heaving and there is very little seating. I always use the Aspire lounge, which is great, but have noticed recently, that this seems to be getting extremely busy, as more & more pax seem prepared to pay, to escape the chaos of the terminal below.
