To ask one last question - a travel agent, who books through his/her own computer a reservation on Air Canada - can

i) book all fares, including freedom and latitude (the latter 2 are considered aircanada.com web exclusive fares) equivalent fares, without going to the aircanada.com web site, for both domestic and transborder flights, and

ii) tango fares, whether domestic or transborder, can not be booked by a travel agent, unless he/she goes to the aircanada.com web site.
