We have a flight from San Francisco to Madrid with a 2 hour connection in Frankfurt. I know this is tight since we will have to go through immigration in Frankfurt before getting our connecting flight, but we are flying on miles and this was one of the only choices with only 1 connection, so I took it.
Does it seem reasonable that we will make this connection? We are flying Star Alliance - United SFO-FRA and then Lufthansa FRA-MAD, so no need to check in or anything - should be quite smooth. There is another Lufthansa flight to Madrid later that evening, and then worst case scenario is spend the night in Frankfurt and go to Madrid in the morning - so I am not overly concerned about making this connection, just curious about the likelihood (i.e. should I have an alternate plan in my back pocket?).
I've never connected through FRA before - do we have to go back through security after immigration or can we stay on the secure side and just go to our connection? Do we have to collect luggage (if we have any checked) and go through customs at FRA or would it be checked through to MAD?
