According to the graphic in this article (
https://centreforaviation.com/analys...s-fleet-411254), the average seat count (all operators worldwide, ranging from 161 to 335) is 245 for 787-8. UA's original configuration is at 219, which is now bumped to 243. This number matches with AA's 787-8 count. Is this just coincident? Please ask Mr. Kirby.
