Because clearly safety wasn’t an issue. There is much you don’t understand grasshopper.....it is never cut and dry.
Let me guess, you’re basing BOS being the best option on all 0 of your hours in command of an aircraft or in airline ops.
If anyone is going to be putting anything in my mouth, it will be myself, dont dont try shoving words in there that never came out in the first place..... i said, and was trying to make a point of,,, Since BOS is also quite large and supports several airlines operating the 787's... WHY COULDN'T IT HAVE diverted there instead of what looks like an insane 180 degree turn in the opposite direction for 3+ hours. So just in case any of that also wasn't clear,,, i NEVER said it would have been the best option, because SHOCKER,,, i DO NOT work in Flight Planning / Airline Ops..... BUT i do know a fair bit about aviation from flying around randomly because i can and and my hours of flying to get my license so i'm not stupid either. As i'm sure many people on here do who either just love aviation or from working in their respective fields within it, So again never said it was the best option,,, it might seem like a better option to ME, but like you so clearly pointed out i dont work in Flight Planning or Ops,, hence my not just saying "Well that was stupid and a waste of time,, should have gone to Boston, end of story Period...."This is supposed to be a forum where people i believe help each-other understand things that are going on, sometimes very specifically,,, and that's what i was doing,, Conversing in a forum, (Asking, questioning, wondering,, thinking and learning) for,, wouldn't ya know it,,, Aviation and related matters.
It’s been answered multiple times by multiple knowledgeable people why BOS was not a great divert point. So let’s go through this step by step.
1) They had some sort of issue that did not allow them to enter ETOPS airspace.
2) Said issue was not a safety of flight issue that required an immediate landing.
3) BOS is not an AA 787 base, nor does AA likely have any maintenance at BOS that is 787 capable
4) Diverting to BOS, while closer in time may cost more time since there are no parts that AA has access to, and no crew readily available
5) The aircraft may have been overweight for a landing at BOS. As it was not an emergency you now have brought a needless overweight landing into the equation which has it’s own considerations
5A) I don’t know what AA’s fuel dump policy is but as no emergency needed to be declared, dumping fuel may not be warranted.
5B) Keeping said fuel in the tanks to burn opens up a lot of options
6) Apparently the weather was bad at ORD so ORD was no longer a suitable option
7) DFW was apparently the closest divert option where maintenance and crews were going to be available in the shortest amount of time
7A) See 5B to see why DFW was now an option
8) If it took 12 hours to get a crew that is probably much faster than had they gone to BOS where parts would have to be transported to, along with the personnel to change said parts, along with a new crew to fly the plane if the original crew times out or is still in crew rest waiting for the repair
9) Just because 787s go to BOS doesn’t mean AA has access to those parts or people that have to know how to change the parts
10) Once on the ground people need to be either re-accommodated or sent to a hotel, perhaps hotel availability and the ability to reroute out of BOS was limited
So off the top of my head those are just some of the reasons why a place like BOS got knocked out. No parts, no maintenance, no crews, possibly overweight, BOS may not be an authorized airport for AA’s 787s in their op-specs for a non emergency.
