LHR-DME-SVX Decided on Transaero as the price was quite good compared to other companies and an excellent safety record. Premium Economy on the outward flight and Economy on the inbound flight. Flew on aging Boeing 737's and decor was faded. We were put in the front row on both legs outbound as we were traveling with our children. However the airline doesn't supply bassinets. The onboard service to Moscow was good with helpful FA's and for the first time I can remember we were given the baby and child's meal I had ordered. The leg room in Premium Economy is excellent and I would recommend Premium Economy on this airline if you are flying with children. The problems started in Moscow. We were told that we had to pick up our baggage in Moscow but we had prepared ourselves for that. However when checking our baggage into Moscow the airline refused to take our buggy past security as they did at Heathrow and insisted it be placed into the hold as luggage. We were told it was either too heavy too complicated or some other reason. The reason was made clear as they said don't worry about having to carry your son because you can hire a buggy which can be taken past security for 200RUB. This is a blatant rip-off and a cheap attempt to make money and the Transaero representative was rude and offensive even for Russian customer services. We felt we had no choice but to hire one and we boarded the connecting flight. The service was not as good and the FA's had a bored and disinterested approach although we did get our child and baby meal again. On our return flight we were told that we didn't have to pick up our luggage at Moscow but that the buggy would have to be taken into the airplane and we would have to pay another 200RUB in Moscow. At Moscow we also discovered that for some reason the check-in assistant had put myself my son and my wife in random seats in the aircraft to London and it was only with a fellow passenger agreeing to move that we could sit together. When another passenger asked what was going on and we explained she just shrugged and said that's what you get when you fly Transaero The service was a bit erratic to London when we asked for a pillow for our sleeping son after take off was told curtly that they had run out and quite a few were impatient with other passengers.The food was quite good on all legs but no drinks runs were made. Only the London Moscow flight had any IFE which was an old Soviet cartoon played on a VHS player. However to listen to it you had to pay 200RUB for the headphones. On the Moscow London flight they were handing out portable media players to watch movies but you had to pay 500RUB to hire one. The trip had some good areas when the service is good it is good. It has the potential to be a very good airline but it needs to be more consistent with its service on the flight and stop trying to add extra charges before and during the flights and as with other Russian airlines it falls down badly on customer service. It is 2-star airline but it could be so much better.
