Narrative:
Aircraft was placed in MEL with one pack operating thereby restricting the aircraft to FL250. Leg was from sat to clt. Climbed to FL330 due to intense en route WX. The pack operated normally for the duration of the flight. The aircraft should not have been sent out in long legs with lines of thunderstorms in the area and restr to FL250.
