airliner tails/ quick easy reference,

yesterday while driving past O’hare, a small what looked like an airbus 320. (small) was pulling up to the International Gates.(all this could be seen from Mannheim Road). the aircraft had red tail and four white squares lined up in a four point square. Without going through thousands of pics at Airliners.net , is there a simplier web address to check on aircraft tails ,quickly? thanks

That was PrivatAir’s (operated for Lufthansa) A319LR all-business class flight to Dsseldorf.

Thank You… I remember the write up on this(business news). That makes sense the size of the aircraft.

Going back to sbord’s question, is there any site that displays a graphic of the tail as a quick identifier of the airline?

does anyone know of a site for quick tail/logos … where to check what airline?
