Somehow I don't think you've experienced the charter airline/tour operator interface directly. It's not quite as simple as you seem to think for an airline (especially a relatively new, non-established one) to dictate what days it'll fly on. Tour operators have particular day-of-the-week requirements. In some cases that's because of weekly self-catering accommodation changeover days (frequently Saturday or Sunday). If the tour operator comes to your new little airline and says "can you quote me for a series of 20 flights to Faro on Saturdays?" he is unlikely to be particularly impressed if you quote him for Wednesdays instead. You need the business. Of course you'd prefer if it were spread throughout the week. But you don't really have the power to dictate that - it's rather naive to suggest otherwise.
Bear in mind that if the passengers are only getting their flight times confirmed in Jan/Feb for the summer holidays they may have booked a couple of months previously, it's likely because the tour operator has only just finalised the flying programme, i.e. which airline is flying which sector at which time.
Yes, it is very sad for all the crew at EIR, and I fully support them, it stinks that because of crappy managment people loose their jobs.
I don't know the Eirjet management. I can't judge how good or bad they are. But I would merely note that this is the same management that set up the company and created jobs for people in the first place, and I notice also that they gave their clients advance notice of their shutdown to reduce the impact.
Companies fail for a variety of reasons, of which 'crappy management' is not the only one. If you have direct evidence that this is the principal reason for Eirjet's demise, OK, but otherwise isn't that a bit of a cheap shot?
