UA 777 out of DXB
I was a pass on a UA 777 from DXB to IAD yesterday. It was very hot on departure and we used most of the runway. Our intial was FL300 because we were heavy with fuel for sure.
My question though is that I thought the UA 777's were all early "standard range" birds with some ER's. Further, I didnt think the ER had the legs for DXB - IAD in the summer months? Obviously I am incorrect here since they are doing it.
What kind of reserves does the UA777 have after this route? Are they weight restricted out of DXB? I thought the UA birds were running 74K thrust PW engines. Seems like they would be marginal at best on this route.

UAL had B777-As (595.0 MTOW)delivered in '95-'98, but now has many B777-200ER IGW birds, capable of 656.0 MTOW, plenty of range for DXB-IAD and KWI-IAD. I think that jet has about 16-hr range. DL flies them DXB-ATL and used to fly BOM-JFK.

Correct. The standard birds are used for East Coast-Europe and domestic. Our IGW airplanes have a TOG of 640. Routinely fly 14 hour legs (DXB-IAD & IAD-PEK) with fuel to spare.
Dubai and Kuwait in the summer can be problematic requiring takeoffs at midnight when things cool down and improved flaps 5 takeoffs.

FL300 is not unusual on a 14-15 hour flight. It is just performance and you will find if you stretch the 767 too, you will be limited to FL300 or FL280 in some instances. Big airplanes that fly long distances use a wide range of altitudes for optimum performance.

I've jumpseat on that flight now 3 times and we usually leave IAD with 200K on fuel and return with 230K. The longest leg I had was DXB-IAD around 14 hrs. Great Flight and the crews are always helpful and happy to have me aboard.

Thanks for the info guys. I was curious because I didn't know that UA had any 777's that would make that run. We did leave on a 12:10 AM departure. I was expecting a 744 though.
I fly the 319LR (corprate charters) and when we pull out of DXB we are heavy on fuel but can still climb to FL320 for initial, however we are always light comparatively because of the aircraft configuration. We can run about 12 hours absolute max from DXB.

DL now has the ultra long range -200LR's as well. We were using them on ATL-BOM for a while - they were a better fit for that route since they could carry a much greater cargo load on the return flight.
