Two Southwest Airlines planes made emergency landings at Oakland International Airport Tuesday in separate incidents.
The first flight, Southwest Flight 3519, took off from San Francisco International (SFO) headed to Denver (DEN) but diverted to Oakland and landed at 7:07 AM due to a cabin pressurization problem.
The 737 had 143 passengers and crew aboard and made a safe landing with no injuries.
Officials said it was easier for the aircraft to land at Oakland rather than return to San Francisco.
The second plane, Southwest Flight 2899, took off from Oakland headed for Reno but turned around after a flight attendant smelled smoke in the cabin area about 9:30 a.m.
That flight also landed safely with no injuries reported.
