I'm in MTY and just at the gate (03MAR / 04h20 CST). I had completed online check-in yesterday.

Systems is up - the kiosks were not working - at least at 04h10 CST.

Unrelated to the system integration my flight to IAH is late due to crew rest I am flying to YVR at 08h45 - arrival is now 08h03 into IAH. If I miss this flight the next non-stop to YVR is at 21h05. I have Global Entry so I'm hoping I can connect quickly otherwise I'll be hop, skipping and jumping across the continent during the day

That's great that this major event seems to going well.

Happy Travels Today.

Cheers
