SWA from Las Vegas to New Orleans Sunday night had a 3 hour delay that got us in at 2:20 AM. Depending on who you asked, the reasons for delay ran from weather to equipment to flight crew. Could not have been weather because the plane was at the gate and there where no weather issues in LAS or MSY. Supposedly a new crew was coming in from Oakland. No offers of compensation in my email the next day. Suggestions on getting customer service related points??
