Can someone answer the questions of the original post? I think these questions have been answered: yes, 24 hours for on-line BP, great idea to come 2hours or earlier, and A, B,C are clearly marked.
1. Can she get all the BP on-line even if there are four of them?
2. If they are told that they need to get tgeir BPs at the terminal, is 2 hours enough time to probably get A BPs
3. Most likey, they will be preboarded since they are travelling with a 2 year old and possibly can further be insured if they tell SW that it's the kids' first time.
We only have flown once with our 1 year old at the time and 5 yo and my wife. We got our boarding pass on line 24 hours prior, got there 2 hours early, took our stroller to the gate and checked it at the gate, were preboarded, sat 3 on one side and me on the other and changed seats with wife halfway and prior to landing, picked up stroller at the gate and picked up our luggages. We got lucky but eveb when everything worked fine it was still hectic. Good luck!
We would probably fly SW one more time after that we will just fly airlines with reserved seating
