Do not rely on receiving an email from Southwest, advising of a change in your upcoming Southwest travel. They are currently making changes - some confirmed by email notifications and others without any notifications. Keep in mind, however, that with or without notifications, if Southwest makes a change in your confirmed reservation, due to a schedule change, you are entitled to make a one-time modification, with no change in fare; you must keep the original city pairs, but are allowed to change travel date (within a 14 day window, either way), as well as the particular flight, subject to availability. If, when viewing your reservation, while logged into your account, you do not see a message indicating a schedule change and advising about allowing one-time modifications, contact Southwest for assistance. You are not bound by a three-day time limit to make changes, if contacting Southwest, even if you do not see that ability to do so, yourself, online.
