Hi- I have a question that I'm sure someone out there can help me with! In April we booked a 2 week family vacation trip to Denver on Frontier Airlines. Today we found out our son has a state baseball tournament the weekend between our vacation. Is it possible to book roundtrip flights from DEN to our tournament location (not the same airport as our home airport) for the weekend, then use our original return flight home the following weekend? I wasn't sure if traveling through Denver between our original return flight would flag something and prevent us from traveling home at the end of our two week vacation as planned. Thanks!
