One time flying back from Europe I had a plane change in Amsterdam at Schiphol. We were there for well over an hour before catching the flight home. We got on that flight, my travel companion, she and I were split up and 100 or so Russians who had missed their connecting flight got to sit together. What we didn't know was, Lufthansa was only concerned with their luggage and no one else's. We took off without incident. Over Newfoundland the Captain casually mentions that a few bags didn't make the flight - those who had barely made the flight might not have had their bags aboard. We got to JFK and it was 2 3rds of the plane had no luggage and my Our Keys were in our luggage, thanks to Alitalia not letting us keep our keys on us and told us to check them in our luggage's and put all coins in the bags as well - (we noted that was odd but we obeyed). We had no where to go and no one to call as it was 3am arrival (before cell phone's were ever popular - with no coins - and Lufthansa wouldn't sell us any change to make a call from a pay phone - spent the rest of the morning in a coffee shop on Madison Ave - finally getting ahold of our Super for the extra set of keys.)
