I am guilty of this every time I fly...Why? Because gate agents don't enforce the policy of letting the FC/Business class tickets board first and I am no longer taking the risk of gate checking my bag. Sorry if I drive you nuts.
But seeing as flight attendants snap at any Y passenger who tries to put a bag in a C/F class bin, that shouldn't be an issue.
On bigger planes, I get it. You want your stuff to be in the bin, not under your seat or in the pit. If you're on a 777 where business is 2-4-2, those overheads are going to go fast among your premium pax. What I don't get is you're on a CRJ-700, your bag is going to get gate checked. Period. First on, last on, its not going to fit, bro. Yet, every flight I ever boarded as a gate agent you'd have 6-10 frequent flyers, in either coach or first, all lined up in the Red Carpet Lane 20 minutes before boarding. Its retarded. "4 hour flight in a regional jet? Bet you I can make it 5 hours if I board early enough!". Bet you can, but, why? Because they're businessmen. Nothing they do makes sense. Do they have a dress code for revenue pax in first? Last I checked, I can sit in first class in an LMFAO shirt and converse sneakers, and that's as an employee. Yet they're standing there, 25 minutes to boarding, wearing 3 layers of expensive clothing in a 75 degree terminal waiting for a flight to Phoenix where its a scorching 105 degrees anxiously waiting to nestle into the cramped and uncomfortable seat which will entomb them for the next 2 hours. Must just be a measuring contest within the strictly secret fraternity of businessmen.
I do love businessmen, I really do. When I was customer service and they'd be yelling at me, I would seriously pretend they were saying "RABBLE RABBLE BUSINESS RAH RAH BUSINESS RABBLE RABBLE" and try really hard not to laugh. Sometimes I point at them in airport terminals walking to my gate in street clothes and go "Whats the business, man?". They always are very taken back. So to any business men who are reading this, thank you. For all you do.
Sorry, hot topic for me. I'm in the process of writing and filming a sketch about businessmen in airports.
