I've only used LPL twice in the last few years. My experience about 3 years ago was so ghastly I didn't think I'd ever do it again. It was heaving with passengers, the access was poorly designed, security staff slow and unpleasant (even if you you gave way and paid the £3 'fast track' fee).
I used it last week as a flight from there was my best option and was pleasantly surprised, no crowds, no delays, even managed to get a reasonable breakfast although for what it was, it was overpriced. All round, not a bad airport.
