I’m still shaking my head that BOS to SEA is a “long leg.”

What do I do?

Write down time and fuel at each fix.

Note the trends in each.

Update winds.

Set up diverts in the fix page. Ask myself “what would I do if....” regarding the diverts, since they are often airports and/or countries I have never been to. So....

I’ll look at the Jepps to see what they have. Look at company notes for operating hours since I’m usually flying all-nighters.

Review NOTAMS for these airports, which are often difficult at best in foreign countries.

Stop reviewing and just look at stars....I can see stuff where I fly that I can’t at home.

Get a crew meal and/or coffee. Lav break. Ask the F/As if everything is good in the back.

Look at WSI and our radar to see if we need to deviate.

Read the complicated escape-route verbage for the Andes if we have to descend.

It’s easy to sit there and do nothing if nothing goes wrong. But as others have opined, I try to give the folks in back...and my fellow crew....the deserved amount of knowledge, skill, and preparedness they deserve if the excrement impacts the impeller.
