Oh great. SFO UCs are getting shut down for renovation. UA is flying way more out of T2. So way more UA flyers will be in the vicinity of the MLL before their flight.

And now everyone and their mother with a CSR has access when flying AC or United.

Ugh.

But also: "Please note: At this time, Chase Sapphire Reserve cardmembers and their guests are not eligible for access to our Montréal (YUL) Maple Leaf Lounges. "

What an exception. Guess the crowding there is too much. But I can't imagine YUL is going to have nearly as many CSR holders as LAX/LGA/SFO.
