German charter airline LTU pursued a rather questionable replacement strategy for their fleet of ten L1011's in the late 80's. Not only did they order about 5 or 6 A330, but also 4 or 5 MD
-11, both with an option for more. At the same time. LTU's fleet also consisted of B757 and 767.
Therefore, during a period between 1991, when the first MD
-11 was delivered, and 1996, when the last TriStar left the fleet, LTU's modest fleet of about 30 aircraft consisted of 5 types from four manufacturers with four different cockpits.
The ensuing troubles to keep such a chequered fleet in profitable operation were further increased when it turned out that the MD
-11, which were supposed to fly on long-haul routes (the virtually equal-sized A330 were scheduled on medium haul routes), offered just too many seats for the longhaul leisure destinations LTU served. Instead, the 767 proved to be the ideal aircraft, both in terms of performance and capacity on most of the routes.
In order to standardize its hotchpotch fleet, LTU decided to withdraw the MD
-11 by late 1998. At this time, some longhaul routes demanded higher capacities than the 767 could provide. Thus longhaul flying with the A330-300 was started, and further examples of the type added. As this wasn't the high-gross weight version of the -300, and the -200 was still a few years away, LTU had to operate the A330 with reduced seating; about 1/4 of the seats had to be left vacant on longhaul flights. Hardly a profit-making decision on low-yiedling charter routes!
To cut a long story short, the situation at LTU has somewhat imrpved over recent years after bankcruptcy was narrowly averted with a much-discussed state loan in 2001.
Nowadays, the MD
-11, 757 and 767 have left the fleet as have some of the A330-300. Instead, further A330-200 were added plus A320/321 as replacement for the 757. Today LTU operated a single-cockpit fleet of just two types from a single manufacturer - A320/321 and A330-200/-300, increasing the economic turnover greatly.
In hindsight, acquring the MD
-11 was a very bad decision, since the aircraft proved to be too big on longhauls and wasn't as economical to operate on medium hauls like the similar sized fleet sister, the A330-300.
But the hotchpotch fleet was just one incredibly obvious dumb decision of the inept LTU management of the 1990's.
