Most airlines give you quite a lot of leeway about carry-on.
If you're really pushing the limits of what's allowable though, make sure you check in to your flight online. This way, you don't have to actually walk up to a counter and run the risk of them weighing your gear, you just waltz straight through to the gatelounge and do your best nonchalant walk through with your gear.
