Whenever I go to BRU I see at least 2 to 3 A330/340 in the Sabena Technics hangar or around it. Sabena has approximately 10-12 A330/340 ; so if 3 are always out of service does that mean that the airline only flies 8 or 9 aircraft at any time.
For instance how many B744s are always flying of the 57 strong fleet at any one time. I also imagine that an airline must keep reserve aircaft in case "active" aircraft suffer from sudden unavailibilty.
Anyone have some interesting insight on this "behind the scenes" aspect of aviation.

Thanks and cheers  Big thumbs up SAA-SAL

It varies with the airline, but generally-speaking, most do not have "reserve" aircraft sitting idle. An aircraft sitting idle (waiting to be used when another breaks) is an aircraft that's not flying and generating revenue. That's just one aircraft--as in theory, you'd need multiple spares to cover your major hubs, but you'd still have to hope that the spare was in the same city where the busted aircraft was.

What occurs most often, and it's all very dynamic, is to cancel another flight(s) that are lightly booked, thus freeing up the aircraft to operate in place of the broken one. This is one of the things that causes the misconception that airlines cancel flights due to insufficient pax loads, but in reality, it's just a matter on taking actions that will inconvenience the fewest number of pax.

P.S. Flights that are in MX (and there always are a certain percentage that are) are not considered as reserve aircraft, as they're not usually available for use on short-notice... For all practical purposes, they don't exist until the work on them is completed...

Cheers...

As much as I know LH always has seven planes in FRA that can jump into service if they are needed. I don't know how they do that or so but I guess if a plane goes into some checking they keep it away from service for a bit longer so it can be ready when needed. Just like with the crews that have stand-by...
I can't promise that this is true I just heard that a long time back.

Godbless is correct, however, LH doesn´t have the planes waiting in case another one breaks, they just have these aircraft waiting to cope with the bad on-time performance many airlines and airports have to struggle with.
so these aircraft are actually utilized to assure that the schedule is being uphold as best as possible all the time and to ensure that on-time performance will be improved. LH´s main hub FRA suffers from a major lack of capacity and so it often has to bear with many delays.

If only pure sweetness was offered, why's this bitter taste left in my mouth.

Do you know what kinda planes are always available? If it is seven planes how are they divided up? How many widebodies, how many single-aisle planes...? Or is it just dependant on the situation how many and what kinda planes are available?
