You can see the terminal information via the [Timetable] function in the KVS Tool:
Interesting. Didn't know that. This is the flights in question:
[KVS Availability Tool 7.0.2/Diamond - Amadeus: Timetable/NL-BCDF]
Code:
SFO San Francisco Intl CA US [KSFO]
LHR London Heathrow UK [EGLL]
THU 02 Aug 2012 - 09 Aug 2012
Carrier Flight From Depart To Arrive A/C St Frequency | Dur'n | Dep T | Arr T | Effect | Ending | Exceptions
--------- ------ ---- -------- ---- -------- --- -- ----------------------------------------------------------------
AC 567 SFO 15:00 YVR 17:11 E90 0 1234567 12:40 I M 01 Jul 03 Sep
-> AC 854 YVR 18:30 LHR 11:40 +1 77W 0 M 3
So, it is an M to M connection. I guess in this case one of the MCT exceptions applies, namely:
[KVS Availability Tool 7.0.2/Diamond - Reference: Minimum Connection Time [MCT]: YVR/AC-AC]
Code:
DD DI ID II
STANDARD: YVR 020 060 060 090
TERMINAL: YVR M TO M 045 050 090 090
M TO S 075 075 105 060
S TO M 075 075 105 060
S TO S 045 050 090 090
EXCEPTIONS:
A/L FLT-NBR TR DEPARR AREA
AC M US --- --- 070 060
AC M
**END OF DISPLAY**
So, it is legal, but just barely (by 19 minutes)
