We booked our return trip from St. Louis on Christmas morning mostly because of the lower price. However, we thought that the plane would be fairly empty. That hope was dashed when we saw the long and getting longer security line after being dropped off at the airport. I do wonder why more airports haven’t adopted the drop-off system at Lambert St. Louis. Cars pull up in diagonal slots, discharge their passengers, and then pull forward into a lane from which they then rejoin the roadway. Anyway, the plane was fairly full. We took two seats in two adjacent rows hoping that no one would want to sit next to kids, but a mother and son took the two aisle seats next to each of us. The plane was packed, and the kept the two last rows empty. We were the sardines of Christmas.
