An American Airlines Airbus A319-100, registration N822AW performing flight AA-505 from Miami,FL (USA) to Mexico City (Mexico), was climbing out of Miami when the aircraft levelled off at FL280. Vibrations developed, the crew reduced the thrust and slowed the aircraft, the vibrations ceased. The aircraft subsequently accelerated again, continued the climb and continued to Mexico City without further incident.

A passenger reported about 20 minutes into the flight, just after levelling off at an intermediate cruise level, there were strong vibrations. Cabin crew, visibly uneasy, stopped the cabin service and announced all passengers should remain well strapped in. The engines audibly ran down, about 30 seconds later the vibrations ceased, the engine accelerated again and the flight continued normally. There was no announcement from the cockpit, cabin crew however reported that the captain told them he had never experienced something like this in 25 years, he suspected ice was shedding from fuselage and engines. There had been stormy weather out of Miami, they needed to quickly climb through cumulonimbus clouds which may have caused icing. The captain would have maintenance check the engines after landing.

Data off the aircraft's transponder suggest the aircraft levelled off at FL280 at about 507 knots over ground, slowed to about 410 knots over ground, then accelerated again to 500 knots over ground and continued the climb.

The aircraft remained on the ground in Mexico City for about 2 hours (about one hour longer than scheduled), then departed for the return flight.
