Delays have been horrific this year across the board from all carriers, this is one thing that cannot be down to cost cutting as safety is paramount. The mergers may be a large factor as 2 flying programs try and work as one and we all know the airport themselves are getting more restrictive taking longer and longer to pass through each year but it still does not explain the smaller carriers Air Malta were more or less spotless until recently.
Airlines need business, especialy repeat business more than ever at the moment so this could not be happening at a worse time, excuse the corporate lingo but our flying programs should synergize by the start of next summer so there should be a much better on time performance albiet with slighly less frequency.
