Furthermore, the main reason why these aircraft have been so successful is because of their acclaimed fuel efficiencies. With fuel prices over $100-110/barrel and with analyst projections of further long-term upward movements, 10 percent -15 percent fuel efficiencies do indeed amount to large cost savings. Nonetheless, fuel today stands at just under $90/barrel, supply is plentiful and there is a cautious calm on fuel price trends within financial and industry circles.

Adding to the above, in 2011, airlines had a decent chance of securing early delivery slots, if they were quick to place their orders, following the announcements on updated narrrowbody models, the A320neo and B737 MAX. With the narrowbody aircraft backlog standing at over 6,000 units, and with production rates stable at 70-75 a month, airlines would need to wait 5-6 years to see their first deliveries if orders were placed today.

Finally, we have to look at the state of the historic large aircraft buyers . Gulf carriers are always prime candidates when it comes to large aircraft orders, for example. However they already have orders pending, which will almost double their existing fleet size.
