Thank you everyone for your input! We did try to utilize advice and sites that I read about on here, but had trouble with Kayak and being directed to a place starting with a "Y" for booking. It made us nervous so we Googled it and stopped with that. I did initially use Google flights to narrow things down, found some flights, then booking options were given.
From ORD to FLR is Lufthansa and could be booked through United....so I went to United site, but couldn't book the return flight. The separate flight thru United was not the price given on Google or Expedia. My hubby and I spent probably 3 solid hours, both of us searching, Googling, etc, to try and make some sense out of it. You have probably figured out we have not booked international flights before.
After looking on Priceline, Kayak, Expedia, we ended up with the flights we have: Lufthansa, ORD to Munich to FLR. Home is Swiss Air FCO thru Zurich to ORD.
We did do an online chat with Expedia afterwards because we were skeptical of the prices and if the itinerary was correct and included us both. It does. The Expedia guy gave us contact info for the airlines for us to contact if we want to try and get seat assignments.
To one comment above, I DID see listings of supposed flights where the connecting flight left before arrival to the airport! That really was concerning and made us suspicious of the whole thing.
I have a couple more hours in which I can cancel the whole thing......from everything above I think we are willing to take the risk for what we consider to be at least half of what we expected to pay.
Any more thoughts? Thank you all so much!
