I am guessing that this is a mistake with the aircraft identification for UAL 1289 from BOS - SFO. I highly doubt it was a 737-200.
United has been sending 737-800 Overwater to Flightaware as a different code than they used to. It hasn’t been fixed in Flightaware’s system yet.
Makes sense. Thanks!
I recently noted that a UA (CO) B737 flight identified as 73S or 737-200. I have a picture of the aircraft and it is indeed a B737-724(WL) using the registration number, I tracked it down and the entry for the aircraft in the FAA registry is wrong! The FAA lists it as B737-224.
And when you search the forum, it’s often better to use Google rather than the forum’s search engine. Add the suffix “site: flightaware.com” to your search terms (no quotation marks).
site:discussions.flightaware.com works even better.
At 7:40 PM CDT on May 19th, Flightaware was still showing 12 737-200s airborne.
