I do believe there is "exclusivity" in the easyJet/LPL contract but it may be a silly thing to say but contracts have never, ever been broken have they?

VLM have announced a 9th London City service starting March with retimings of all services - there are now to be 4 depatures to LCY before 8.30am (and they still show 12 return weekday services when "booking" them in July.)
