# What does the ATC term “a company traffic” mean? [duplicate]

During my flight training I often heard the term "a company traffic" in radio calls from the ATC like:

N123AB a company traffic is joining downwind runway 24


What does "a company traffic" mean? Why not just mentioning the type of the aircraft like:

N123AB traffic a Piper Archer is joining downwind runway 24


Note: I'm flying in Europe (Switzerland), so maybe it's only used by ATC in my area.

• Having listened to some live ATC (feeds from US-based airports) I've always heard that as "a company aircraft" which I assumed to mean an aircraft from the same airline (with the same paintjob). – ratchet freak Apr 3 '19 at 11:21
• Okay that would make more sense to me, so I'll change the question. – Pascal Ackermann Apr 3 '19 at 11:22
• Additionally, what I've heard/understood of ATC (admittedly very little, as I'm not a pilot nor in training), is that it is "company traffic", not "a company traffic". Of course, that could be due to listening to native English speaking controllers in the US vs multi-lingual controllers in the EU. – FreeMan Apr 3 '19 at 11:49
• @ratchetfreak based on everything I've learned here, that would be the answer. You'll get more magical internet points that you can redeem for rainbows and unicorns if you'll post that as an answer... – FreeMan Apr 3 '19 at 11:50
