DL sometime around 2006. ATL-LGA was delayed 3 hours, finally took off. About 2/3 of the way there (probably close to 11pm at this point), we diverted to PHL b/c all NYC area airports (JFK, LGA, EWR) were closed due to severe storms and high winds. Sat on the ground a couple hours before they announced LGA was open. BUT flight crew had timed out so we were waiting for a new crew. Finally on the ground at LGA around 3:30am. Line for cabs into the city was LONG. Finally got in a cab around 4:30am and just as we crossed the Triborough bridge, cabbie hit a huge pothole and blew out both tires on the passenger side. He wouldn't call us another cab, but we got lucky and a cab driving by picked us up. Got to the hotel at about 5:30am with meetings to start that morning at 8am.
DL in 2011. Flying DEN-MSP-ORD and on the second segment, noticed that we were flying straight past ORD, then past downtown, and out over the lake. I knew something was up, although no announcements had been made. This was NOT the usual holding pattern. Halfway out to Michigan, pilot turned us around and finally made an announcement that the landing gear was stuck and wouldn't fully deploy. Came in for an emergency landing, complete with emergency vehicles lining the runway. My wife was freaking out. Fortunately, nothing came of it, other than the delay and having to be towed to the gate.
