just stop. You are proving you don't know what you are talking about again. You need to learn the differences between the non-242T airplanes and the 242T airplanes. It isn't a simple paper work change.
I'm well aware that it is a paperwork change and I said as much but it was one that wasn't available from Airbus until recently and it also doesn't increase the thrust of the engines.
and as 700 noted, not all 330s were eligible for just a paperwork upgrade. Some had heavier landing gear and brakes from the factory. and I don't think US' 330s are 242T models because Airbus just provided the option with the factory build 242T models.
DL operates longer sectors than ATL-Brazil on the 333 (SEA-ICN, ATL-FCO) but SEA-ICN is taking significant payload restrictions right now.
All of those cities above or lower altitude than ATL-GRU. it is possible that with the runway extension at GRU, the numbers work now but they didn't for years.
DL intentionally did not use the 330 at GRU because of the MTOW issue.
DL has wanted to have a single ~300 passenger aircraft on ATL-GRU for years and the 77ER/LR has come to GRU on more than one occasion but the 330 has not.
When you factor in the reduction from one ATL-GRU to two but on a larger aircraft as well as the addition of MCO-GRU, DL's GRU capacity is fairly constant except from the SE. DL is reducing DTW-GRU as well as the total number of seats to BSB which are partially offset by the larger 330 to GIG.
Feel free to verify the baggage weights but they are higher per passenger to/from Brazil than from other countries.
My statement above is completely correct. The only way that the 333 works to/from Brazil is by increasing the takeoff weight.
and you will also note - if you care to look - that DL is sending the 333 to MUC which I also believe it has never been used for - although IIRC the 332 has been used there. MUC is a couple hundred feet higher than ATL but not as high as GRU and again the only reason DL can do that now is because of the higher MTOW.
FRA also will get the 333 from ATL.
