Looking at the aircanada.com websaver deals of the week and saw http://www.aircanada.com/en/us/offe...bsaver_fares.html?src=hp_wn#SFO-INT_US-SFOLHR ... SFO-LHR is only $278 each way I know this fare looks way too cheap to be true, but how bad is it? I randomly chose depart Mar 02 and return Mar 07 SFO-YYZ-LHR-YYZ-SFO (approx 11,630mi) Base fare: $302 + YQ $292 = Subtotal $594 (not bad ...) Canadian taxes: AIF $29.34 + HST $3.81 = $33.15 US taxes: Agriculture $5 + Pax Facility Charge $4.50 + US Federal Customs Fee (wat?) $5 + 9/11 Fee $2.50 + US Immigration User Fee $7.00 (wat??) = $24 UK taxes: UK Pax Service Charge $36.89 + UK Air Pax Duty $96.23 = $133.12 Wow .. just wow ... I've always heard how expensive it is to fly out of LHR but o...m....g.... they charge like 4x Canadian taxes!!
