The only locals who can afford to travel by air with children are New Russians. They barge to the front of every queue, airport or not, with children or not. This has always been the way for Russians who think they are the elite. The Communist Party officials did it, and before them the Czar's family and nobles did it.
Sorry spiney but WHBM is pretty close with his observation. My wife (Kazakh) does it also, much to my embarrassment. But for her it works, she has no shame, and I tag along without the usual tedious queueing. She is very much a "new" Russian in some respects, but hardly rich or elite, just brazen.
And thread creep? Maybe, but then again perhaps of interest to anybody who gets pushed aside in the process.
