7E7 will offer airlines a new airframe (they can't fly the same old
ones
forever)

No ?

No. Aircraft have definite service lives. Surprised you did not know
that.

What's the service life of a DC-3?

Don't know--how many of them have you seen flying with major airlines of
late?

Why would the number of major airlines be at all relevant?
