Ok I am flying out Sunday from PHX but right now I am in Vegas, which will be an hour time difference on Sunday but same time as Vegas right now
Travel alert ion app says we can check in 23 hrs prior to flight not 24 which I find odd
Anyway if my flight is 750pm PHX time what time can I check in Pacific time?

I'd say to try all possibilities, and maybe your flight is late enough that people with PHX departures will report earlier. Right now there's an alert on the Southwest site:
It may need to be determined what happens for Arizona and some international locations not doing DST.
If you are traveling on Sunday, November 5, you must wait until 23 hours prior to your flights scheduled departure to check in and receive your boarding pass. See you onboard soon!
I've gone back and forth on this, but I think they have it wrong. Is it, like apparently in spring, "the time on the clock Saturday is the same as departure time Sunday," at least in places going off DST? Let's say my flight is at 7 a.m. Sunday, and in these DST days, that's the time of sunrise in my area. But on Sunday that will be an hour after sunrise. Putting it another way, the hour between 2 and 3 a.m. happens twice. The true T-24 would be at 8 a.m. Saturday (an hour after sunrise), but if checkin opens at 7, isn't that really T-25? T-23 at 9 a.m.?It may need to be determined what happens for Arizona and some international locations not doing DST.

Would be interesting to see what happened with this if WN ever had a flight taking off between 2-3 am on Daylight Savings Days.
IT department would explode.

Anyone understand the concept of UTC/GMT? (I.E. Greenwich time) World time zones vs. local time?
Airlines, the military, and other industries that operate across multiple time zones use a single "world" time, rather than a local reference, precisely because of this daylight vs. standard issue.
Find out the UTC of when the flight departs, then check in 24 hours earlier, regardless of what the clock says at any particular location. (By the way, this works equally well both in the Spring AND Fall)

OMG. Every year, same thing. Does anyone at Southwest even know how Daylight Saving Time affects their systems?
A few days ago, they posted a Travel Advisory that said:
Now, the Travel Advisory says:
A previously posted Facebook update that reflected the former message appears to have been deleted.
Has anyone flying tomorrow tried checking in today yet, and can provide some actual info?
