UA849 on Friday, SFO-IAH, was showing as the A/C from UA415 DEN-SFO leading up to the flight until about 30 minutes before. Then it switched to something arriving from EWR. UA415 was >30mins delayed inbound so that may have been the reason, don't really know. In any case 849 pushed on time and into IAH more or less on schedule.
3/4 flights this weekend were largely on time. Did have a one hour delay on IAH-FLL due to late arriving a/c from SAT -- thunderstorms in TX on Friday night were cited as the cause.
