Summer seasons can often be a trying time for charter operators. To keep costs down you have to have your aircraft flying 24/7 for 6 months of the year and there are often odd technical or weather delays. A delay at the wrong time of the week can have a knock on effect for days on end coupled with ATC slots etc. If the charter companies had spare aircraft lying around for such contingencies then your average package holiday would cost a great deal more. Personally I suspect they were having a bad week and you should leave it at that.....but I stand to be corrected.
