Part 5/9:
The Journey Across the Atlantic
With the flight continuing, the aircraft eventually cruised at a lower altitude of 27,000 feet, consuming more fuel but otherwise maintaining stability. As two hours passed, everything seemed to be going well until they reached the eastern coastline of the United States, where new challenges arose.
Air traffic control denied a request for the preferred flying altitude due to the presence of other aircraft, forcing the crew to alternate to 29,000 feet. As the plane crossed the Atlantic, they encountered a forecasted headwind which negatively impacted fuel consumption predictions.
