I'm one of the passengers that filed complaints (multiple) going back to 2019. And it hasn't improved any recently IMO, at least not at DFW where since May, I've had to file multiple complaints including taking 2 hours to get from check in to my gate - and almost missing a flight, to actually missing a flight because the wheelchair attendants kept delaying and then once they caused me to miss the flight wanting to abandon me at the closed/empty gate, yelling and arguing with me when I wouldn't let him abandon me, and then there was the one who got angry at me because I couldn't walk up the jetbridge.
