Sushka - Let me correct myself.
The first three 762's were UA
. The fifth plane was DL
's, and flew on 2/19/82. However, DL
was the first to use GE
engines, so they were the launch customer for the Boeing/GE variation. I believe Ethopian Airlines, of all airlines, was the first to get the 762ER, in 5/84. JL
placed the first order for the 763 in 1983. AA
was the launch customer for the 763ER.
