Delta has been awesome enough I favor them for flights. Their employees at MSP saved my vacation three times. One helped us find our way around airport construction at MSP. The next helped us when Houston had some internet outage and all airlines had mile long lines to check in/bags. Finally my wife got a severe migraine and I somehow put a bag down at the gate and forgot it and an employee turned it in and I was able to just go pick it up instead of having the airport locked down or whatever happens when you lose bags in 2023.
