Airlines still publish standard fares that use the booking class of
Y/J/F. Those are often used for standard interlining. So if BA wants to
bring a passenger to canada and then buy an AC ticket for the domestic
leg, it wll buy a Y fare with some industry discount (add-on fares).
So Air Canada has made its standard Y fares extremely expensive so that
airlines that are outside of Star Alliane and who wish to buy Ac tickets
will base their add-on fares on some very expensive base fare,
while those part of Star will have access to lower fares becase of code
sharing deals. |
