Southwest is known for it’s A, B, C lettered check-in policy where the letter on your ticket indicates when you can board. A relatively well know secret is that you can print your boarding pass online up to 24 hours prior to departure and likely secure a coveted ‘A’ boarding pass. This was recently, not sure how recently, changed from ‘midnight the day of the flight’ so when I went to print out a boarding pass for my flight to Orlando tomorrow morning at 7AM, I unfortunately was hit with a ‘B’ boarding pass.
We won’t be making this mistake on our 6 hour trip, four hours flying, to Lake Tahoe. You are permitted to check-in luggage even if you print the boarding pass online. If you don’t have to check in luggage, then you can just go to the gate directly.
