They are serious about having only 2 items when you walk on board. It doesn't matter how small your purse is.

I would not purchase any food on these flights because they are expensive. It is best to bring your own snacks if you want to save money. Download movies onto your phone or tablet, don’t pay for their expensive WiFi! Check in on the airline’s app 24 hours prior so that all you have to do is print your luggage tags. Add your boarding passes to your phone. No more paper boarding passes which is more convenient.

Southwest seems to board and unload about as smooth as any airline - carry on items seem to work as smooth as any airline I have used. Southwest also does not charge to check bags which seems to encourage people to check bags instead of bring an enormous carry on item that does not fit well in the cabin.

Don’t be that person who holds up the plane because of your carry on. Whether putting in over bin (able to lift it on your own) or refusing to not listen when space is full and need to check it.

We landed on a domestic flight in C terminal, and had an international departure from Terminal E. FYI, the food and drink selection is better in C, so if you have the time don’t rush to your departure gate.

Be prepared for the disorientation of SeaTac as the entire terminal appears to be under construction. It’s unnerving.

Book with a long gap if you have a connection on another airline. My flight from Phoenix was only 1 hr long but there was an over 2 hr delay in boarding. Luckily I allowed a 6 hour gap between flights for my other flight leaving overseas or I would have missed it. Many people like me fly one flight to LA which has a lot more international departures because it’s a lot cheaper to break the flights up than to book them together . So it’s important that flights are somewhat on time especially between different flights not connected with one booking.

Asheville airport under construction; this flight was unloaded by ramp or stairs (can't remember) on the tarmac close enough to the building, but you are exposed briefly to whatever the weather is be it wind, rain, cold, etc.

Waymo (Google's driverless robotaxi) is operating the the Phoenix area. Pricing comparable to Uber/Lyft, but no tipping since no driver. It is a novel experience and worth trying of your route falls in the service area. The PHX airport (at least Terminal 3) is really lovely, clean, and bright. The Skytrain (free, runs between Terminals, and transit stations every 5 mins or so) is excellent as well.
