Hi, I have a flight from MXP to LAX via WAW. I will be needing to visit customs to get a stamp for VAT refund. Is customs located in the Schengen area of the airport or in the non-Schengen area (or are there locations in both)? And to confirm, there is a customs office located airside, correct?
Also, I have a 90 minute connection time between flights (both in business). Will this allow me enough time to get my refund paperwork processed? I emphasize that I'm flying business because I'll be the first off the plane (I'm in row 1) in WAW and boarding for my US bound flight should be relatively quick (at least this has been my experience every time I've flown business coming home from Europe).
