Regarding the problems last Sunday night/early Monday it really is a viscous circle.Firstly the queues at immigration are not the airport's fault. Not enough staff employed by the Border Agency - write to Maybot (ex Home Secretary) and good luck with that. Now we come to the delayed flights, passengers want the cheapest fares so the airline has to get the best possible deal with the handling agent or if self handling keep the costs down to a bare minimum, so if flights are delayed after the end of the main shift the handling agent will be reluctant to pay overtime due to any profit been made seen to go out of the window even if some of the staff are willing to stay on. So you end up with the scenario of last Sunday/Monday unfortunately. It will not be just a Stansted problem other airports are going to be in the same situation in the weeks to come and you can do nothing about the weather!
