A few weeks ago I mentioned that United was moving up the timetable for the retirement of the 747 fleet. They have now released a few more specifics, including what appears to be the final flight of their last 747.
The final flight is slated to be United UA892 that is scheduled to depart Seoul, South Korea at 10:25a on October 29. The ‘outbound’ leg to this turn will be October 27 and will be United UA893 that will depart San Francisco at 10:55a. A 777-200 is showing as operating the route beginning on October 30.
Keep in mind that events like this are subject to change and may not happen as they are currently planned. However, if you want to take the chance to take one of the last flights aboard a UA 747, round-trip Economy tickets are pricing in the high $600 / low $700 for these final flights. Business Class is in the $3800-$4200 area.
With the date change, that means the final flight of a United 747 is currently scheduled to depart Seoul Incheon for San Francisco on October 29, 2017. Though there was 1K inventory for saver economy earlier this week, shortly after the schedule became public.
