user: your San Antonio baggage agents are kinda terrible. And the text for my delayed flight from Dallas to Detroit pissed me off! This mean I won't get home till about 2 am and I work tomorrow. What is wrong with you that's over a 2 hour delay
agent: We're so sorry to learn of your frustration this afternoon, Sara. We would be glad to get you a status update on your flight. What are your Flight # and destination?
user: Dallas to Detroit 6278- now only 2 hour delay but I know how that works! Your gate agent Jason is great he tried to find anything to get me back earlier and couldn't find anything. Sorta makes up for your baggage agents
agent: While we encountered unscheduled maintenance on the aircraft, it looks like we're doing everything we can to get Flight #6278 moving to Detroit this evening. Hang in there!
user: Thanks! Not super confident in that response about technical issues Hope your aren't charging for drinks on the flight cuz getting on a plan that was delayed 2 hours for unscheduled maintanace kinda makes me nervous.
