(A) Some airline companies prefer to spend extra money on leather seats for their aircraft, sometimes twice as expensive as the others, because they last two times as long.
Dependents caluses are seperated through the commas therefore it distorts the meaning
(B) Some airline companies prefer to spend extra money, sometimes twice as expensive as the others, on leather seats for their aircraft because they last twice as long.
Similar reasoning as A which distorts the meaning even twice long usage is absolutely right
(C) Some airline companies prefer to spend extra money on leather seats, sometimes twice as expensive as the others, on leather seats for their aircraft, being twice as long lasting.
The addition of comma after other isn't required since these are continous statement and with being it's usually a red flag
(D) Leather seats lasting twice as long as the others, some airline companies prefer spending two times the extra money on them.
The starting gives away it completly makes the sentence akward
(E) Some airline companies prefer to spend extra money on leather seats, sometimes twice as expensive as the others, for their aircraft because they last twice as long.
This nails the twice usage and the meaning is also absolutely perfect
Therefore IMO E
