3,788 miles. 7 hubs. 1 day.   Last year, a group of enthusiastic MileagePlus members had the idea to fly to *all seven* of our U.S. hubs in just one day. This year, we turned their ultimate AvGeek adventure into our newest annual tradition.   Congratulations and thank you to everyone who helped make the 2026 7 Hub Run such a memorable marathon! 🙌   #AvGeek #Travel #Marathon #Aviation #UnitedAirlines
