Here's a rather long story about what has become a total mess of a trip. Originally, I was booked on YYC-YYZ-EWR-LIM in Business on June 30 / July 1 thanks to this deal EdmFlyBoi found. Not relevant to the travel disruption, but relevant for context, I also just arrived in YYC on June 30 after repositioning from MEX-YUL-YYC on June 29 with an overnight layover in YUL.

My original itinerary was as follows:

• Jun 30 AC154 YYC-YYZ 23:30 05:15 (+1)
• Jul 01 AC8872 YYZ-EWR 06:30 08:00
• Jul 01 UA886 EWR-LIM 14:30 21:25

Since I had all-day layover at YYC, I'd been monitoring the status of my flights. As late as 18:20 YYC time, everything still showed as on time. But AC154's inbound aircraft, AC153, was suffering rolling delays at YYZ so I started getting nervous, knowing I had a tight connect at YYZ the next morning. I contacted YYC Concierge via the MLL agent at around 17:30, and they invited me to visit the Concierge office. There, the very friendly Concierge team (shoutout to Nadia and Mandy) started looking at alternate routings for me should I misconnect. With no great options available and Concierge receiving word that AC153 was finally boarding around 18:20 YYC / 20:20 YYZ time, we decided to just stick with my original itinerary. 5 minutes after I return to the MLL at 18:25, I receive the text / e-mail / app notification that AC154 was delayed to depart at 00:40 and arrive at 06:25, meaning I would miss my connection to EWR. (It turns out AC153 didn't end up leaving YYZ until 22:12, almost 4 hours behind schedule).

I immediately get back in touch with YYC Concierge, and we find a relatively acceptable option:

• Jul 01 AC324 YYC-YUL 12:25 18:16
• Jul 01 AC98 YUL-BOG 22:45 04:00 (+1)
• Jul 02 AV49 BOG-LIM 06:50 09:55

This would require an overnight stay in YYC and arriving in LIM a day (~12 hours) late, but with AC agreeing to cover hotel, meal, and ground transport in YYC (and with no better options available), I agree to it. The problem: YUL-BOG is already oversold in Business, so Concierge needs to call Revenue Management to secure me the ticket. (Interestingly, tickets for the one-way trip were still being sold on AC.com for ~$3,500 in Business Lowest and ~$7,500 in Business Flexible.) Eventually, they're able to issue the ticket for me. Unfortunately, AC98 is being operated by the dreaded C-GFAF (perhaps a last minute equipment swap can actually work out in my favour this time?), and AV49 only has Economy (and the 3 'Premium' rows upfront aren't even eligible for seat selection), but at least (barring further delays), I can still make the most of my time in Lima. Obviously a crappy situation, but definitely one of those cases where having access to Concierge (especially locally and 'on-demand') came in very handy.

A few questions for the experts here:

• Am I entitled to delay compensation given I'm now slated to arrive ~12 hours later than my original schedule? Maybe $1,000?
• How is SQx earning going to work with this revised routing? My original ticket was on United stock, so I was expecting no SQD (but yes SQM) for the UA-operated EWR-LIM leg. With the revised routing, will I still earn the original routing SQD? Or will I earn more SQD given more of the trip are operated by AC now?
• My new boarding passes have a 014 ticket number, but oddly, the printed boarding passes only say AC*G and don't reflect my SE status. The in-app BPs don't even recognize *G status and show 'None' under Frequent Flyer. The Apple Wallet BPs also don't reflect my *G / SE status, but if I click on Pass Details, it does show *G. Concierge assures me my FF number is in the system and they also can't figure out why the BPs are not reflecting it. Should I assume SQx crediting will not happen automatically? This seems to have resolved itself.
• An alternate routing would have had the BOG-LIM leg on LATAM, which did have Premium Economy available (whereas AV only had Economy). Would I have earned AP points or SQM on LATAM if booked through AC? It didn't look like a codeshare flight.
