I'm in the KLM Crown Lounge near the AMS B gates about to board my flight for WAW in about an hour. The flight from YVR was okay, didn't get an UG but did get ample legroom in the bulkhead. One funny thing at YVR was that I had to have the gate agent print out my KLM boarding passes since I connected from AS ... instead of just printing out YVR-AMS and AMS-WAW, it printed out those and tomorrow's WAW-AMS pass (seq. no 1!). The gate agent said, "wow, that's a quick turnaround! ... oh ..." as if to think, "oh great another MRer"
I Googled "weather in Warsaw" and didn't realize it's for Warsaw, Indiana

. That said, they are likely very similar. I'll report on the actual conditions later tonight.
I'll be returning to AMS tomorrow on the early afternoon flight and staying near Centraal Station at night in case anyone else is doing a mix of WAW and AMS this weekend.
