Attached please find two screenshots of the aircraft details page of the two planes.
Both are 767-300ERs with 14.5tn above standard MTOW with blended winglets installed. Theoretically, both should have the same nominal still-air range (6470nm), but the range figure for one of the planes seemed to be unchanged after the installment of the winglets (which gives an additional 200nm range).
The aircraft IDs are 21958 and 19155 respectively.
Thank you.
