When Boeing or Airbus specifies Maximum range for an airliner model, does that not include the required reserves, or is that an absolute maximum including reserves? For example Boeing claims a 3265nm range for it's 737-900ER, Is it's absolute range limit 3265nm, or is it more like 3500-3600nm inclusive of required reserves? Thanks

I don't have a source but I would assume it's maximum range with reserves. So the maximum you could legally fly as for a planned flight and land with required reserves, certainly assuming standard atmosphere and zero wind conditions as well.

On the website it usually shows range charts with average winds and with reserves and what the passenger/cargo loading is.

This shows range charts fror the 737 family

Interesting that you can go JFK-LHR apparently. As the 737 is more a short to medium hauler in my thoughts, I am always hesistant to think she could make it across the pond easily. EDIT Actually, I just checked out the 777 charts, which has an INSANE range, and it makes me kind of uncomfortable waiting for the next great T7 add-on that's in the making.

They are used on a lot of trips to hawaii which is a similar distance going across the atlantic.
