Good start, Joe. Care to clean up those two incorrect ones?

102. Where would you be if you were enjoying a beer at the Sourdough Bar?

Enroute to Seat 2A's adopted state, on an Alaska Airlines Convair 880.
Incorrect The 880 had a First Class lounge but not a bar, per se.

23. You need to relocate from Mexico City to north of the border. No, not that border! The other border – to Montreal, Canada. You’ve flown between these two cities many times and have generally been quite pleased with the service you’ve received aboard Canadian Pacific. Still, variety is the spice of life and so you decide to try another airline that offers a two-stop direct flight between Mexico City and Montreal. Identify that airline, the two enroute stops and the aircraft utilized.

This would be AeroMexico's DC-8 flight MEX-DTW-YYZ-YUL.

Si, Señor! Muy bien!
