You are correct, the trips on the 900 are more efficient. Never said they weren't. But I know 200 guys who are sitting 9-20 days of reserve as newhire said, and 900 guys who are sitting 6-9 months of reserve. Some like that. I'd rather be flying inefficient trips than sitting on reserve. Maybe after I get tired of the job, sitting in my underwear at home and making guarantee will have a new appeal for me. There are two sides to every story, and we are just throwing them out there for folks to understand so they can make a better decision.
There's a reason there are 20+ year EDV CAs who have only flown the 200, and it's not for lack of opportunities. There is an appeal in the 200 for many, just as the 900 has appeal for others.
