I just learned that if you are taking a connecting flight(s) to a destination, ensure that you are doing so with the same airlines and have ample time between flights with the necessary boarding passes.
There is no direct route from Vancouver, BC to New Orleans, Louisiana so I flew to Los Angeles via Air Canada to connect to United Airlines at LAX. There was about 70 minutes to spare and I was not issued my connecting board pass in Vancouver. As luck would have it, the 1st leg was delayed by 35 minutes and, of course, the United Airlines gate was on the other side of the airport at Los Angeles. LAX is a large airport.
And then there was the security check all over again with the full body scanner.
You guessed it. I missed the flight. United Airlines re-booked for me but now I had to fly to Chicago and connect to New Orleans. Instead of catching the opening ceremonies and dinner extravaganza, I ended arriving just in time at midnight for bed at the hotel. Oh, and I got up at 4:30am to leave for the airport to catch the first flight. I did get to my final destination safely, just a bit late and tired but all ready for the Coldwell Banker conference!
I hope that my return flight would be smoother.
