One of my life's little delights is hearing from Air India - their frequent flyer program, to be more specific. The latest email, informing me that they have upgraded their fleet, does not disappoint at all:
"You, no doubt, know that our daily non-stop services from JFK operate with new 777-200LRs, and our daily flights from Chicago with 777-300ERs." (emphasis mine)
I can see a pop quiz at the airport before checking in.
AI Officer: "What aircraft will we be flying today?"
Officer: "FAIL! EPIC FAIL! Back of the bus! No poori-chole for you!"
(then turning to the stewardess, with a sneer on his face):
"Foolish civilians! The answer we are expecting is - "the longer-range 777-300ER and 777-200LR variants entered service in 2004 and 2006, respectively, while a freighter version, the 777F, first flew in 2008. Both long-range 777 models and the 777F are equipped with General Electric GE90 engines, wingtip extensions of 12.8 ft (3.9 m), and raked wingtips."
