There was even a mid-flight proposal on the plane’s upper-deck (she said “yes”), USA Today reports.

“The iconic 747 is a remarkably special aircraft that signaled a new era of air travel and was equally recognizable and beloved by our customers and crew alike,” said Oscar Munoz, CEO of United.

“While today is bittersweet, we’ll continue to honour the Queen of the Skies’ game-changing legacy of connecting people and uniting the world with our next-generation of long-haul aircraft.”

Delta has also said 2017 will be the final year of service for its fleet of B747s. The plane is still flown by British Airways and Lufthansa among other major carriers. In total, 489 B747s are currently operated by commercial airlines worldwide.
