hi - planning trip (for 2) from Nashville (BNA) to STJ this mid-may for a week, staying in bay cruz area. need to make flight arrangements. would leave/return either on a sat or sun. would like to minimize risk of missing day on STJ b/c of flight delays/changes; delayed luggage, etc. as have read about here. from bna, looks like US Air (through charlotte/CLT) or American (through Miami) are main airlines (comparably priced). I know to leave at least 45 min b/t connecting flights (and would leave more if flight schedules enable). we (2) will likely have 1-2 bags total to check. Worry over flight changes makes me wonder if we're ok to plan villa rental around what flight times/days show, or if we need to arrange flights and villa rental so have a night/off airport layover in CLT or Miami built in, which seems to create 2 separate flight bookings, rechecking luggage, fees. I don't think change/delay would be issue on return if only issue is extra $ for night stay on STT?, but would hate to have worries w change going. any thoughts appreciated - e.g., 1) if we allow the 45 minutes (and plus) b/t flights, do you think we'll be ok? 2) if airline changes so have to change days at villa, how do rental folks handle/what do we do? 3) is one airline better than the other for risk of change/delays/luggage issues (mid-may)? thanks much for any insights.
