Suitcase on the bus?

I travel for the first time on Monday and was wondering how other bus riders handle going directly from work to the airport. I'm grabbing a ride to the airport with someone I know from the customer - would it be weird to ask to stop my apartment to grab it if it's not super out of the way? It feels lame as hell to bring a suitcase on the bus and then hide it in my office all day. Advice appreciated in advance.
