The final two sections of my flight log are classes and tail numbers.

Classes

The class listing is one of the simplest; it’s just a table of the travel classes (first, etc.) that I’ve flown and how many flights I’ve flown on each.As of the time of this writing, the vast majority of my flights have been domestic, so I’ve rarely ever been on three-class planes. Thus, I have not yet had any flights in business class.

As always, clicking on one of the classes shows a table and Great Circle Mapper map of my flights in that class:

Tail Numbers

Every aircraft has a unique number painted on or near its tail – think of it like a license plate for an airplane.

Because the number is unique, if I keep track of it, I can tell whether I’ve been on a particular plane before. And, of course, this also allows me to track which particular aircraft I’ve flown on most often:

My tail number data is more sparse than a lot of my other categories. I didn’t begin tracking tail numbers before 2012, and even once I did, it’s not always possible to see the tail number (for example, at night, or when the airport terminal layout blocks the view of my aircraft’s tail). Still, the above listing shows me all of the aircraft that I know I’ve flown on at least once.

Clicking on one of the tail numbers shows a list of my flights on that plane and a corresponding map:

And with that, I’ve fully described the basic functionality of my flight log. Go forth and explore!
