Just be glad that you get to see lots of aircraft Tony....Look at YUL they are soooo underserved they don't see much!!!
I agree with you totaly, but its good in a way, if you are a traveler, you can get to more destinations using one airline, did i tell you that the flight that i was on to miami was a code share with United and Mexicana. AC took us there but it was cool to be on United and Mexicana flight XXX, i think it was like AC916 or some 900 series flight (btw 7:00am weekday flight)
Drive it like you stole it!
