Donder10 - upload with the airline name that appears on the airplane, which in the case you mentioned is El Al. If you want to add a comment about NAA that's up to you. As CC32 says, use the hybrid colours checkbox too.
On a related subject, there was an Excel Airways 767 appeared on the database this morning with the airline name set to Air Atlanta Icelandic - to be honest, that's the wrong way of doing it.
CC32, if it says Burlington, upload it as Burlington. Again, if you choose to put a comment that its operated by EWW, that's up to you.
We have to use the name on the side of the plane - if we were to go any other way, we'd end up with thousands of pictures in the database showing as "International Lease Finance Corporation" or "First Security Bank of Utah"...
There are old pilots and there are bold pilots, but there are no old bold pilots
