Hi,

I am fiddling with the Matrix software to get the quotes for my flights from LON-SIN in July, but it seems like the software is listing LH and LX fares which are much cheaper than what is listed on the usual booking sites (airline sites, expedia, hipmunk etc), or fares which just cannot be booked using the sites.

For flights departing on 21 Jul and returning on 30 Sep:

London (LCY) to Singapore (SIN) - Mon, Jul 21
Deutsche Lufthansa AG 935 - Deutsche Lufthansa AG 778
Singapore (SIN) to London (LHR) - Tue, Sep 30
SWISS 4311 - SWISS 318

£665 on Matrix, but £1800+ on SWISS's site. On the site note, this combination cannot be booked using the other sites either.

Another example:

London (LCY) to Singapore (SIN) - Mon, Jul 21
Deutsche Lufthansa AG 935 - Deutsche Lufthansa AG 778
Singapore (SIN) to London (LHR) - Tue, Sep 30
Deutsche Lufthansa AG 779 - Deutsche Lufthansa AG 900

£791.51 on Matrix, but more than £800 on LH's site

Another example:

London (LHR) to Singapore (SIN) - Mon, Jul 21
SWISS 327 - SWISS 178
Singapore (SIN) to London (LHR) - Tue, Sep 30
SWISS 179 - SWISS 316

£652.95 on Matrix, but more than £800 on LX's site

Is this some sort of error? I am thinking of calling LH and LX to try and get these fares, but I won't be too optimistic about the prospects, given the huge differences in the quote prices.... I believe that this may be due to the fare rules and restrictions.
