HiFly might take ex SIA A380-800s. But some people speculates that HiFly might take MAB A380-800s instead, noting lower maintenence cost as MAB’s oldest A380 is just about 5 years old.
From the lastest speculation, the plane will be fitted with 560 seats in 2-class configuration. It’s highly likely that HiFly will retain the interior. But if they take SIA frames, the plane wouldn’t be fitted with Suites due to this reason
“Suites portion are proprietary and property of SQ and not the lessor, and SQ will not be selling them on.” - Airliners.net
The main problem is, taking A380 is a risky decision, especially if you take SIA frames which are more vulnerable to problems and needs more frequent maintenence check. A380’s maintenence is more expensive than other aircrafts such as A330 and A340, one of the reason is because A380’s population is much less than both aircraft types
Can HiFly take the risks and able to maintain the A380? As it would be very risky to lease A380s as few airlines are interested to lease them.
