What is an "L" in front of an "N" tail number


#1

Hi:

I am trying to figure out what is the meaning of the letter “L” in front of some flight data I got from the FAA; if I try to look it up with the “L” I get nothing, but without it, there is data.

The ‘L’ number is next to a normal “N” tail number, they are in 2 consecutive records with almost identical data, but either the arrival time or departure time is different. I noticed that the records that have it are for LJ type aircraft. I was thinking perhaps it means “Late”? I googled it, but cannot find an answer.

Only certain records have it, and I am not sure what they mean, here are some samples:

Aircraft ID ETMS Flight_Index Unique Flight_ID Date Departure Airport Departure Date (GMT) Departure Time (GMT) Arrival Airport Arrival Date (GMT) Arrival Time (GMT) User Class Aircraft Type

Thanks in advance,
