Ok, maybe what I did was not the best idea, but....
I purchased a roundtrip ticket LAX-AMS on Continental while the fare was extremely low because I was unsure if my final destination would be PRG or ZRH. After it became clear that my final destination would be ZRH, I purchased a roundtrip ticket on Swiss Air with a departure from AMS 3 hours after my scheduled arrival on Continental. Now I am starting to worry what will happen if my Continental flight is delayed causing me to miss my Swiss Air flight. Is there anything I can do now to protect myself in case such a delay were to happen?
