Hi I would be traveling with Family of 4 on Southwest to Orlando in coming weeks. Did not think of it earlier but now that I am getting ready for the trip, I realize I only have 40 Minutes layover at Denver. Should I be worried about it and get it changed or in case of some delay, will Southwest help me in not making it a hassle? This is an award flight, so tried to change it but it needs more miles which I would have to buy. I do not have enough miles at the moment.
