Few months ago, Airbus threatened to sue Boeing for falsely claiming the
A340 could only cruise at around 0.78 Mach.  A few days ago, I browsed
through the schedules of three airlines (Lufthansa [LH], Cathay Pacific
[CX] and Singapore [SQ]).  I'm not really trying to make a point here.
It's just some trivial information.  Here's the comparison:

LH:

I found Frankfurt-Osaka being only route on which LH uses both the
747-400 and the A340-300.  LH allotted the same gate-to-gate time for
both aircraft types.

CX:
                         747       340      difference
Hong Kong - Toronto*:   17:15     17:45        0:30
Toronto - Hong Kong*:   18:35     18:45        0:10
Hong Kong - Rome+:      12:40     13:25        0:45
Rome - Hong Kong+:      12:20     12:40        0:20
Hong Kong - Jakarta:     4:15      4:20        0:05
Jakarta - Hong Kong:     4:30      4:35        0:05
Hong Kong - Manila:      1:50      1:55        0:05
Manila - Hong Kong:      2:00      2:05        0:05

* The Toronto flight makes a technical stop in Anchorage.
+ CX does not regularly operate the B747 to Rome.

Also, CX flights to Singapore, Kuala Lumpur, and Bangkok are five to
ten minutes slower on the A330 than on the B747.  The gate-to-gate
time for these three destinations varies from 2:45 to 3:55.

SQ:
                         747       340      difference
Singapore - Melbourne*:  7:00      7:25        0:25
Melbourne - Singapore*:  7:40      8:15        0:35
Singapore - Sydney+:     7:15      7:40        0:25
Sydney - Singapore+:     7:55      8:20        0:25

* The Melbourne flight is currently being served with the A340, exclusively.
+ The Sydney flight will be effective as of July 1.

SQ's schedule shows all its flight to Jakarta and Bangkok having the same
gate-to-gate time, irrespective of the aircraft types.
