Thierry Pouille and his wife, Sophie, run Air Journey. They accompany or arrange flights for people with capable airplanes and outsize — some might say outlandish — travel dreams. For instance, while we were rambling around some of Europe’s most intriguing destinations, their daughter was shepherding a round-the-world tour. On one day, Air Journey had 18 airplanes in the air. On our trip, Thierry was the briefer, confidant, fixer, slot negotiator, hotel room wrangler and restaurant chooser. I came to look forward to his briefings given the night before a flight. The company, using Jeppesen FliteStar, SkyVectors and ForeFlight, prepared flight plans. Safety, as you will see, was given priority.
