I’m wondering if anyone knows the answer to this. Sorry, I’m going to be long winded …. Here’s a little backstory…Heading from JAN (Jackson, MS) to MCO in 3 weeks. It’ll be me, my husband, 16 yo, 18 yo and 2 yo grandbaby. We first purchased a 1:10 pm flight with a 3 hour ATL layover and then lands at MCO at 8:05 pm. Well the more I thought about it, I decided we needed to take an earlier flight so I just switched us to a 7:30 am with a 40 min ATL layover that lands at MCO at 11:55 am. Here’s my dilemma.. now I think I must be crazy for changing it because that 40 min layover has me worried because we’ve never flown or stepped foot in ATL before so I’m not sure how the layout is or how far apart the SWA terminals are, plus we will have a 2 year old. We did buy EBCI when we originally booked in July, but obviously we are not sure of what our position will be yet. And seeing how if we aren’t really close to the front of the plane, it could take forever to get off it having to wait on all the people in front of us to get off. So basically IF the flight is actually on time and there are no delays (which I’m not very hopeful about) on the first part, we have about 10 minutes to get in line for the second part of the flight if we are in the A boarding group since it boards 30 min early. Is there anyone that has experience with this short of a layover lately or thinks this is doable as is or is it too risky? If I were more confident that the plane wouldn’t leave us stranded in ATL if we did have any kind of delay, i wouldn’t worry about a thing, but unfortunately last year we almost got left at MDW on the very last flight out that night due to our first flight being delayed, but not the second flight. We were running as fast as we could, my daughter was crying, and they were about to shut the door on us when we came through screaming like crazy people at the attendant to let us on - we barely made it. We do not want to ever go through that again if we can help it. My poor daughter was traumatized and then she had to sit by herself with strangers, which freaked her out. I wish they’d bring back daily direct flights again!

I don’t think JAN is a big airport or would be crowded on flights, but we’ve never flown from there before either so who knows.
Now, I’m also contemplating upgrading to business select tickets so we are guaranteed A1-A15 boarding so we know we will be able to sit close to the front and get off quickly, but that comes at a $600 cost for the 5 of us, assuming we also have to buy it for the 2 year old to board with us? What I mean is, if the 4 adults have business select, but not the 2 year old, would he be able to board with all of us or would someone have to stay back in the line to wherever his boarding position is? We are so new to flying with an infant, we don’t know all the rules. Is it worth that and if we did upgrade, would we be able to be refunded for the EBCI that we already purchased since we would no longer need it ? I know you can upgrade to A1-A15 at the gate for less money, if available, but that’s not a guarantee either until you are there. Is there a way to know how full the flight actually is besides just watching the prices ? I’d hate to wait too long to upgrade to business select and the prices be even higher than now. It’s all such a gamble and I’m just not a gambler!
I appreciate any words of wisdom and advice on what would be our best option.
