Welcome to the registrations spotters club!
There are not so many here in the US that just log the registrations and not take pictures but I'm one of them. You can see me almost weekly at Imperial Hill at LAX
but at different days each week.
I write the registrations down in a small notepad and then later transfer it to my JP
book. The JP
is really great and has a lot of info. The new one should be out in June or July so wait until then to get one.
In the notepad, I note the date and location.
I log registration numbers and don't keep track of frames seen. If the aircraft changes airline, I'll log it again even if there's a merger. (I will soon have to log all of US Airways aircraft when they are transferred to American....).
Set up your own criteria and make sure to use Flightradar 24 a lot which helps with the registrations of the aircraft that are too far away.
Perhaps we'll meet at LAX
