I heard they are a decent company. They had a rough start due to a Chinese operator that did not respect the contract clauses and got out of the deal, but they are focusing on flights to the French Antilles at the moment. They also do ACMI on behalf of LOT out of Warsaw. I don't know if they are still flying for BA. The management is not new in aviation, they founded TNT in 1999, so they know what they are doing.
Not the best paid job in the industry, but if things keep going well for them, that can also improve in the future.
