I feel like I have to bring this up because it was very odd the way the Frontier agent was communicating to people waiting to complete check in and check their bags. While I’m not complaining about the agent trying to get late people checked in and to their gate on time, I did find the method of her yelling and asking people if they weren’t listening because she’d already called the city out, or saying other non-professional type comments to be, well, very non professional. I realize people show up late and then wonder why they’re missing their flight, and that can be frustrating at 6 am as a Frontier employee. Telling people they should have hurried, or why weren’t they paying attention, or any other personal opinion related comments are not producing a professional image of the Frontier Check in agent. This is based on one agent this morning at Denver at 6 am. I have no idea of the name and I fortunately didn’t have to deal with her. I had a very helpful agent and was checked in professionally and kindly. While I stood as the next person in line, the agent I’m referring to tried to lift a bag, shouted about how heavy it was, then started clapping her hands demanding some other Frontier employee come handle the bag and help her. It was as if she was working in one of those bars where the wait staff cuts your tie off, makes rude, but not mean, derogatory comments “to make you feel like you’re at a family ruinion with the cousins bashing each other”. As far as travel and being tired and wanting to just check in and move on, I found it disruptive and not enjoyable to hear this lady yelling at everyone for the 30 minutes we waited in line. I personally don’t find that to have left a positive image.
