It was a combination of a lot of things that made it a bad experience.
As mentioned the entertainment was terrible, a few grainy screens playing old fashioned Russian movies.
They served the same kosher "meal" a few times on the way there and the way back. This consisted of frozen Tuna, stale roll and something unidentifiable that was probably supposed to be warmed somehow.
Rude in-flight service.
When we landed in Russia we were put into a big empty stuffy room with no chairs or food and made us wait there for probably 1-2 hours staring at the 4 walls- although it felt like much longer.
Finally they started processing us through security to go through the airport to the connecting flight. The sensors on the metal detectors were probably set to the highest level so that every person set them off ( -they were probably set off by the mercury we digested with the tuna). This led to the full body massage that would put the TSA to shame.
There was one woman agent there processing us and since it was a plane full of mostly frum (chassidish) Jews, you can imagine the uproar when she came at the men with her gloved hands. (The looks on their faces probably resembeled a patient going in for a colonoscopy). They could not understand why they needed to get a male agent to take over and she was actually chasing some men trying to give them the full groping..
The women also had to fight her from trying to rip their sheitels off their heads because the pins underneath were setting of the handheld wands. No sensitivity shown, and no understanding why someone wouldnt want to get half undressed in public along with the deep tissue massage...
Basically it felt like these people were used to dealing with cattle and subhumans and just didnt "get us".
I know some of the above is not an issue with "Transaero" themselves but you get why I just have a bad taste in my mouth from the whole thing. The worst part was spending a month in Israel with the looming thoughts in the back of our minds of what awaited us for the return trip.
