Southwest, unlike many of the other airlines, does not open up their flights 330 days in advance. Instead, every so often they extend their reservations system a few months out at a time. As of today, you can only book flights through the beginning of January.

However, Southwest just opened up their reservation schedule to allow you to book through March 7, 2018. This means you can now book flights for MLK weekend, February Vacation, Presidents weekend, etc.

Those peak holiday flights increase in price quickly, so if you are looking to book a flight for that time frame I suggest booking now! And remember, there is little harm in booking Southwest flights as early as possible since there are no change fees. You can read more about the exact process and steps to go about this with these two blog posts: “Changing and Canceling a Southwest Flight” and “If a Southwest Flight Goes Down in Price…” But essentially if you…

  • Paid for the flight… You will receive a voucher for the difference in fare price to be used one year from the date the flight was originally purchased (NOT the date the change process took place). This voucher is non-transferable. The voucher will be tied to the confirmation number of the original flight. There is NO fee for this.
  • Booked your flight using points… The difference in points will go back into your account immediately. Again, there is NO fee for this. This is why I love booking Southwest flights using points!

Also, keep in mind that Southwest no longer allows duplicate bookings. There system can now detect a reservation that is booked at the same time as another reservation and will automatically cancel your flight. And remember, if you need to change one of these flights at a later time you are better off canceling and re-booking.

Where are you booking?!
