Recent Traveller Feedback
My suitcase came in at 58 lbs at the Denver counter on my flight to Phoenix — the limit is 50 lbs per bag. Bags between 51 and 70 lbs get a USD 100 overweight fee on Southwest, and I had to pay it on top of everything else. The agent said anything over 70 lbs costs USD 200. A cheap luggage scale at home would have saved me the money.
100 USD
Booked a Basic fare from Dallas to Chicago out of habit and totally forgot bags are no longer free on Southwest. I paid USD 45 for my first checked bag at the airport, and my wife's second bag on the same booking cost USD 55. If you need two bags, do the math — the Choice Extra fare with two free bags can work out cheaper.
45 USD
Flew Choice Extra from Denver to Las Vegas with two checked suitcases and both were completely free — it is now the only Southwest fare that still includes two free bags. My roller plus a big duffel each stayed under the 50 lb per bag limit, and the 62 inch linear size rule was no problem for standard luggage.
Traveled Atlanta to Tampa with our toddler and gate checked the stroller for free — Southwest lets each ticketed customer traveling with a child check one stroller plus one car seat at no charge, at the counter or right at the gate. We kept the stroller through the terminal and picked it up at baggage claim after landing.
One thing I still love about Southwest is there is no published weight limit for carry-on bags as long as you can lift the bag into the overhead bin yourself. I packed my 24 x 16 x 10 inch roller pretty full for a quick Houston to Austin trip and had zero issues at the gate. Just measure it — wheels and handles count toward the size.
