"Apart from Check In TAROM is fine"
My initial experience of TAROM at T4 was not the best. Having checked in online OK through their website I thought armed with my Skyteam Gold card I could simply go into the separate Skyteam business class check in area and drop my bag off. O no no no. The person behind the Alitalia desk said this was not possible today but I could ask at the Alitalia desk in front of the normal check in queue. However it was absolutely chaotic so I joined the TAROM economy queue. There were two check in counters open manned by Alitalia ladies. At one desk two schoolkids obviously had a problem with checking in but instead of asking them to stand aside they were there blocking one check in desk for the whole 20 minutes I queued up.
Once on board the full Boeing everything was fine. On board service was fine and the inflight pasta meal was OK and wine and beer free of charge.
The internal flights from Bucharest to Timisoara and back were fine. They use a Boeing which is just as well as it was full. There is just time for peanuts and a soft drink during the 40 minute flight.
The only slight downside of the flight back to LHR from Bucharest was the slightly chaotic check in - but there was a large party of school kids.
All in all TAROM is fine.
