Possible engine trouble causes UA 810 CUN-LAX Sun 7/10/2011 to divert to TUS

This was United 810 which departed Cancun MX at 5:54pm and arrived in Tucson at 8:15 PM. It appears that United sent a replacement plane - an A320 - from Albuquerque, NM at 9:42pm arriving in Tucson at 10:26pm. (That is not a normal flight listing on their timetable.) They departed Tucson at 11:42pm and arrived in Los Angeles at 12:50am Monday 7/11/2011. (azstarnet.com) Plus d'info...
