What Were the Flight Numbers of the 9/11 Planes? Full Guide to the Four Flights
By Alexander Ross
Q1: What were the exact flight numbers of the four planes hijacked on 9/11?
A1: The four flight numbers were American Airlines Flight 11, United Airlines Flight 175, American Airlines Flight 77, and United Airlines Flight 93.
Q2: Why did all four hijacked planes depart from East Coast cities heading to California?
A2: Transcontinental flights required full fuel loads, between 9,000 and 11,400 gallons of Jet A fuel. The attackers chose these flights so the planes would produce catastrophic kinetic impact and prolonged structural fires upon hitting their targets.
Q3: Are these four flight numbers still in use by American and United Airlines today?
A3: No. Following international aviation custom for fatal air tragedies, both American Airlines and United Airlines officially retired flights 11, 175, 77, and 93 immediately after September 11, 2001. They have never been reissued.
