I feel the need to off myself now.
Is this really that big of a deal? FWIW, I'm on an E90 in 30 minutes, no biggie for me. I lived on this plane for a while.
For every single one of my flights, the curtain has been closed. I've lost count how many E90's I've been on, but YEG YYZ was a route I did almost weekly earlier in the year. It was an E90 every time.
YYZ SEA and return was a E90 too. Never an issue.
