It's the end of an era.
United Airlines' historic Boeing 747 aircraft — famously known as the "Queen of the Skies" — took off from San Francisco for Honolulu on Tuesday, marking the final time that the airline will use the massive jetliner for commercial travel.
United's fleet of 747s has been shuttling passengers around the globe since 1970, according to the airline.
United is replacing the 747 aircraft with much fuel efficient and cost effective airplanes, according to the airline.
In order to relive the glory days of the aircraft's first flight more than four decades ago, United Airlines celebrated the final flight by stepping back into the past. Flight attendants dressed in retro uniforms and the more than 300 guests onboard were treated to a 1970s-style menu.
Tickets for the final flight went on sale back in September, according to the airline. Those tickets sold out in less than 90 minutes.
