Hello Jeff,
We're headed down the 30th, and have the Thanksgiving holiday in our testing window as well. My wife is in healthcare, and works for the largest system here in the Detroit area. She checked through her sources, and was told the labs will be fully staffed and working as normal through the holiday. 24/7/365 operation. They did say that testing supplies like reagent are getting tight. They have seen test results for PCR's slip from 24 hour turn-around to 48 hours due to the increase in testing numbers, but see no issue in getting us our results in plenty of time to get it into the portal unless something changes drastically.

The allowable testing window starts at 120 hours before your flight departs if direct, or 120 hours before your connecting flight inbound to SXM and we're going to do everything we can to stay within it. Much depends on the lab your test provider is using. Most large hospital systems have their own labs, and their affiliated doctors and urgent care locations can use them. CVS, clinics and unaffiliated urgent care facilities and the like use independent labs like Quest Diagnostics, which have widely varying processing times based on location and demand...even how often the lab courier picks up at your test location has an impact. If they pick up at noon and you get tested at 1pm, there goes 1 day right there. We're actually going two different routes just for peace of mind. My doctor pal says the Quest in our area is turning his test results in 72 hours from pick-up right now. Best of luck, safe travels.
