We have updated 15 data models that use the T-2 source.  It is, along with the Form 41 5.2, one of the most useful data sources for our models. Subscribers can browse these using the link above.

Here is one of these models for you to evaluate. The focus is on fuel burn and allows you to compare OEMs and aircraft sizes (regional, single-aisle, or twins).  Press the play button to see the model work over the years.

Let’s focus on two pages and single-aisles for example:

Page 1 – Seat/Miles/Gall and Stage Length

  • The fuel burn performance of the A320 and 737-800 are really close.  As are the A321 and 737-900ER.  Notice the substantial fuel burn improvement the MAX and neo versions offer.  The A320neo is showing +24% and the MAX8 is showing +33% improvement – remarkable numbers.  We would suggest that 100 seat miles per gallon is the new yardstick to beat in single-aisles.
  • Note the A220 performance – +50% better than the 717, +13% better than A319 and matches the 737-700. And that’s the A220-100 at Delta.  When the A220-300 enters service the numbers will improve. 
  • The A321neo at 105 seat miles/gallon is the most fuel-efficient among the single aisles. The performance is driven in part by the long segments flown by Hawaiian which truly exploits that aircraft’s capabilities.

  • The A220 is clearly a step-change over the 717 and E-190.  It would be great to see how the E190-E2 compares when it enters US service.
  • Notice how the MAX and neo are also step-change improvements over predecessor models.
