Guess what! It took me some 5 minutes to retrieve all the information you wanted out of this post on their web-site.
Just go to
If you don't understand Spanish, no worries, an English version is available. Just click the icon on top of your screen.
If you are interested in the fleet operated by the company, subsequently click on the corporate icon on the left hand side of your screen, and select 'fleet'!
You can now see all the types operated by AR, among which, the B747! Click on the picture and you can even obtain more information.
Should you wish to know about the seats and cabin lay-out, absolutely no need to make a post about it on airliners.net... a virtual tour is available on the airline's web site.
Now, was that easy, or what?
