Thomas Cook Airlines - NEVER AGAIN!

My wife and I flew with Thomas Cook Airlines from Manchester to Varadero, Cuba, departing on 10th April 2015 and returning 24th April. We have flown with Thomas Cook Airlines several times over the years - NEVER AGAIN! We have noticed, over the last few years, the airlines practice of offering the opportunity to pre-allocate your seat by paying an additional charge. So we've waited for the airlines to start deliberately splitting couples and families up.
It's started!
At check-in at Manchester Airport, we were allocated seats next each other. However, one of the cabin crew came down the aisle followed by a couple, and told me "there has been a mix up at check-in, these people have paid for your seat". I showed her my boarding pass, clearly printed with my seat number, and explained that everybody on the plane had paid for their seat! She told me that these people had paid extra to pre-book their seat, my argument wasn't with them and I gave up my seat, to sit in the row behind my wife. The member of cabin crew explained that - according to Thomas Cook Airlines definition - this was classed as "next to" my wife! These seats were in a central 3 configuration, and the lady next to me, in the middle seat, told me her husband was five rows back! The lady on the other end of the three told me she had asked for a window seat next to her husband, she was placed in an aisle seat two rows in front of her husband!
The return flight started in similar vein. We were allocated seats in rows one behind the other. These were in a middle four configuration, so imagine my reaction when we found that my wife was seated next to family of three, and I was in the row behind next to a couple. Simple solution - I waited until the passenger arrived for the remaining seat next to me and asked him if he would swap with my wife, which he was only to glad to do. As we were doing this, we found out that half the plane had swapped seats in order to sit with their friends and families. This Mass Musical Chairs totally confused the cabin crew, who had no idea who was where.
Add to this the fact that you now have to pay for headphones, pay for entertainment, pay for meals (this was a joke, the cabin crew had a list of who had ordered meals, but this bore no resemblance to the seating list they were supplied with). Eventually, they just handed out meals to anybody who wanted one!
Sorry, Thomas Cook, you're losing customers with your greed. Even Ryanair tell you in advance you're going to get ripped off - they don't pretend it's anything else, certainly not a benefit or an upgrade which you are trying to pretend you are "offering".
Never again!
