Vancouver International Airport is the only airport I've been to that has different customs requirements depending on your arrival airline.
Some airlines' passengers have to clear two rounds of customs when transiting through Vancouver to the United States. First, they clear Canadian customs; next, they clear American customs (so their onward flight arrives as a domestic flight).
Passengers on other airlines (including Lufthansa) can skip Canadian customs and proceed directly to the American customs line. Much, much faster (even though Global Entry is only available to the double-clearance group) - which got me to Air Canada's Maple Leaf Lounge even faster.
Air Canada Maple Leaf Lounge, Vancouver
Air Canada has no international first-class product, so the Maple Leaf Lounge doesn't have a first-class section. It does, however, have a shower - a great feeling after a long flight.
There are several Maple Leaf Lounges in Vancouver International Airport - this one only houses passengers headed for the United States. It's quite large - it was never more than 20% full when I was there.
The food and beverage selection are very good for what amounts to a domestic business-class lounge.
Mid-shelf self-serve bar
Sandwiches for people
Salsa, hummus, guacamole
Cookies and fruit
Counter, dining table, club chairs
Conference room watched over by owl
So I used the free airport wi-fi, which was only slightly better. But that's OK - I was only in the lounge for a short time before my flight to San Francisco began boarding.
The lounge is good but nothing special - certainly no reason to arrive at the airport early. But if you've got a connection, it's a better place to wait than among the cacophony of duty-free shopkeepers plaintively asking, "Smoked salmon, eh? Maple syrup, eh?" Eh.
