if I was good. Not happy that I have to pay extra money to get the seat I need for lake room, but I guess that’s a sign of the times.

if I was good. Not happy that I have to pay extra money to get the seat I need for lake room, but I guess that’s a sign of the times.

Great flight. Good snacks and drinks. Grateful it was free. The flight from Nashville to louisville, i think her name was Tracy (not sure that's right) super awesome, nice and cheerful. She really enjoyed being at work today! She was the person who scanned the boarding pass on flight wn941. She should be recommended for a raise !

Southwest was greaat! The most expensive but the least upsetting for those we were flying to see.

I was supposed to be on a later flight. When I showed up at the gate, the woman working there was extremely helpful getting moved up to this earlier flight.

Flight was on time. Wi-fi was a little spotty/slow. Boarding and exit were efficient.

The weather could have been better. There was a 40 minute ATC delay in SFO because of marine fog and a micro cell storm delayed landing and take-off at Nashville. The gate was changed 5 minutes from boarding from gate B3 to gate C23 at Nashville airport.

My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.

Wi Fi was horrible kept cutting out the whole time and too expensive

Boarding was a little late, but made up for it. It was quick to taxi to the runway, since it's a smallish airport.

At time of arrival to the airport, there were plenty of kiosks open/running for checking and baggage tags. While waiting to drop my bag, a team member was checking everyone's IDs against their baggage tag to verify a match/compliance to save additional time when dropping it at the front of the line. This was actually a really big time saver and greatly appreciated! Once boarding was starting, the team member had a clear and audible voice with their announcements, with direct (yet friendly) instructions for the boarding process. Once actually boarding, the flight crew gave genuine greetings while walking on board and were very nice and attentive during the flight. The take-off and landing were one of the smoothest I've had in MANY of years. Kudos to the pilots! I literally cannot remember the last time a had such a smooth landing :D
