The confirmation put Chicago on the calendar.
I was flying from Denver to Midway on Friday, May 19. The return was Monday, May 22. I booked it more than a month ahead and filed the itinerary in Gmail.
The message is all logistics. Airports, dates, times, and the private confirmation details that do not belong on a public site. There is no story in the body and no note about what I planned to do after I landed.
That made the reservation easy to miss among the other mail. The same account had SimAuthor test messages, hardware purchases, job applications, registrar notices, and travel confirmations moving through it every week.
Work was busy. Westar had announced the SimAuthor acquisition two weeks earlier. I was still running the network and systems in Boulder. In March I had also sent a batch of applications for Linux, network, and consulting jobs.
None of that turns the ticket into business travel. The confirmation does not mention SimAuthor, an interview, or a client. It only gives me a route and four days in May.
The booking is useful anyway. Travel email fixes the dates before the rest of a trip has a chance to scatter into photos and messages. This one says I bought the ticket on April 12, left Denver on May 19, and planned to come home on May 22.
Chicago was booked. The reason would show up in the weekend itself.
For now, I had the ticket, the dates, and another month before I needed to be at the airport.
