OK, sure, I plugged this into a sim flight planner (http://onlineflightplanner.org/ http://onlineflightplanner.org/). This is on a Dreamliner.
Heathrow - Changi: 63933 kgs
Heathrow - Tehran: 26957 kgs
Tehran - Changi: 39580 kgs
So at least based on this it's not too much of a difference, only 4% more with a stop. (Tehran looked to be roughly in the middle on the flight plan between London and Singapore.)
- izacus 3y agoInteresting, I'd expect it to be a larger difference considering how much the carriers avoid stopovers. Maybe the fees and organization of refueling tips the balance?
- bombcar 3y agoCarriers don't want to do a stop unless they're offloading and onboarding passengers, so they'd rather run one flight to the intermediary, and another direct.
- izacus 3y agoWell yeah, we're talking a about WHY it's a problem for them to stop.
- coryrc 3y agoIIRC airframe lifetime is rated in pressurization cycles.
- cyberax 3y agoIt adds a surprising amount of time. You have to descend, land, taxi to a fueling area, refuel, taxi, take off, climb. And that's if the local regulations allow fueling with passengers on board. That's probably around 2 hours extra. And this in turn can require the plane to carry additional pilots and flight attendants.
