While I haven't seen any traffic or security queues this year, so can be classed as an improvement, what continues to get worse are the queues to get aircraft actually airborne into congested airspace above Luton. Aircraft can queue on the taxiways for a good 30 minutes with massive gaps between departures even when there is nothing on approach. This is the airport that plans to double aircraft movements but has offered no solution in solving congested skies.
Looking at flight radar Luton seems to get particularly affected while Heathrow, Gatwick and Stansted doesn't. Yes they have queues but the queues move while at Luton they often don't.
