Two AA flights that have been around since at least 1966 are AA flight 1 and AA flight 21. Both are JFK to LAX. They were 707s in 1966 and 767s today. AA 1 was the morning flight and AA 21 the evening flight. For a time AA 21 meals were catered by the 21 Club of NYC. The fare back in 1966 was F $160 and Y $145 plus tax each way.
