Most comparisons are to the 777LR which let you have range, cargo and passengers. The 350-900 forces you to pick 2 of 3, especially the first dozen. The -1000 should cover 3/3. One of our remedies for leaving packs behind on the -900 was to remove 31 total seats while increasing the number of D1 to be revenue positive. Instead of leaving Sydney with 30 open seats now we go out full with 8 more potential D1 ticket sales.
