The 747-400 at certain weight/alt combos will clip along at M.88 (I seem to remember that at FL310 - not very often, I believe it was at high FMC factor and into a v. strong Japanese jetstream).
The 777 will do .86 no probs, as will the L-1011 (let's not start the perennial "on-the-step" discussion).
Citation X....anybody?
I've flown the TU154, and can't believe that bucket of bolts would out-run an L-1011 at max TAS alt of about FL280, where CX used to cruise them.
