Hello there--I am a student from the United States currently on a mission trip in Loja, Ecuador. A family emergency has arisen and I need to return to the United States as soon as possible and must arrange via web, as my communication is very limited here. **Please point me in the correct direction as far as how I can go about changing my ticket, and how I can do this without paying the full price for another. **My flight plan was from Loja to Quito with Tame airlines, which I will change with that airline, and then from Quito to Panama on Copa airlines operated by United, and from Panama to Houston and then on to Kansas City with United.**Will this be a problem since the first flight is also with Copa?**The original return flight is booked for July **th with confirmation number AWPJFN**Thank you, and please be in touch as soon as possible. **-Rachel Heitmann
