We're flying to Destin this summer, and the flights we want all have a layover in Dallas. We have options of a 1hr 5 minute layover or a 1hr 45 minute layover. Is a 1hr layover long enough? We will have a 10 month old and 3 yr old with us too, and flight will be through Southwest. Our flight leaves at 7:30 am to get into Dallas so I doubt it would be delayed but I suppose you never know.
