Meeting point in Lisbon Airport?
 

My friend is flying on another airline and we want to meet in the Lisbon airport. What's a landmark that's a good meeting spot???

I would choose the coffee shop to the left (on the way out)of the main enterence/exit of the airport. There is also a wine shop very close to the coffee shop if you get bored waiting.

Enjoy your trip!

Beautiful advice :-) If you get bored, then visit the wine shop :-)

I'm not 100% sure on this, but I think the wine shop noted in tico's post is at the arrivals part of the building.
What I would do if I were meeting someone at the Lisbon airport is to meet right outside the automatic door that takes you out of customs/immigration into the waiting area. When you go through that door, you can either go down a ramp to the right or a ramp to the left. You could just agree to meet at the bottom of one of those ramps. The arrivals area is not too large and you won't have trouble finding each other, so long as you stay in arrivals.
