Technically, no, since the policy states a person preboarding may have one person go with them and you are seeking to have two people go with you, BUT I highly doubt Southwest would require you to split up if you inquired about all preboarding together. This is one of those situations that is going to require a decision made by the gate agent so you should prepare for either scenario. Here's the preboarding policy I am referring to: "We will allow one travel companion to act as an “attendant” and preboard with a Customer with a disability. In most cases, the Customer requires assistance from only one other person, and any additional family members or friends are asked to board with their assigned group." The policy does have the caveat, "In most cases", so there's room to allow for an additional person. I do think if you ask nicely about it and show that the 2nd person is a 6 year old you won't have any problems. If however they are not allowed to preboard with you then there is no guarantee they would be able to sit with you. If you are sitting anywhere but the first couple of rows then you should be able to save seats for them. This is very common, just don't try to save the front row. To reduce the stress of this you could purchase EarlyBird Check-In for your husband and kid so they get a better boarding position. You could also purchase upgraded boarding at the gate to get in the A1-15 positions. It's more expensive than EBCI, but does get a better position. I would suggest going to the gate, inquiring about preboarding, then if that fails, purchase the upgraded boarding positions for husband and son. Still, check in right at 24 hours before departure time to get the best boarding position possible without paying, perhaps it will be low enough for you not to worry. --TheMiddleSeat
