I explained that I always am able to fit the bag into the bin with room to spare, and the agent wouldn't relent. After I argued a little more he said I could try it in the bag sizer and if it fit, I could bring it on... So I try it and it fits perfectly into the sizer and he still said it had to be checked. I thought this was absurd and I brought the bag down the jetway with me, but I tore off the tag and put it up in the bin anyway as usual.

Just curious why the agent would single me out and do this for no reason? Not only did he insist on checking the bag for no apparent reason, but he was quite combative and aggressive about the whole situation. Is there any policy that they are following here?
