International one way pricing
 

I seem to recall that at some point one-way pricing on Air Canada was half of round-trip pricing on basically all fares. This is no longer the case, at least in the sense that tango standard and flex fares do not seem to be available for one-way itineraries, but are available for round trip ones. This takes us back to the days when it was cheaper to buy a round-trip ticket and throw away the return leg, rather than to buy the one-way. If it helps, I'm looking at EZE-YVR one-way fares 11 months from now (don't ask).

Domestic and transborder tickets yes but not Int. AC fares which are still sold as round trip.

Why is that? I know many times I want to fly to Europe on AC but return on another carrier ie/ BA AF AA etc. It's like your stuck with one carrier with the crazy high one-way fare...

Precisely because of this.

There must be something else, which I get the airlines wants to roundtrip fare could it be an ICAO or IATTA ruling because all airlines are doing this..

Aeroplan redemptions one way are 50% of round trip miles but the same calculation does not apply to paid fares unfortunately. Additionally it can easily be very different in one direction from the other internationally. Airlines will charge what they believe they can get away with :(

My thought is that it's because airlines are liable for the cost to fly the passenger back to the point of departure in case of entry refusal/deportation.

Respectfully, JD, this is not the case for all airlines. Westjet, for example, sells transatlantic one-ways on the cheap, without roundrip requirements. I've booked many in recent years.

Ok good to know! BTW I like your handle Norcanair...that's going back a lot of years, a good airline too!

Good eye on the handle - thanks! The first airline I ever flew. Was too young to speak of its comparative quality, though dad flew it weekly and it came to be known in our home as Tincanair. I suspect that was more his deep sense of irony than anything else, though.

And just to stay on topic, I've bought a few one-ways on Transat YYZ-GLA at normal pricing, iirc.

R/T fares are combinable on a half R/T basis with another half R/T fare that is also combinable.

So you can take half a PRC90 and half a ZRC90 to create a P outbound and Z inbound round trip.

But you cannot take half a PRC90 to create a one way fare, unless PRC90 is also published as a one way with its own specific cost.

Check China. Asia has quite a few. For TATL it's mostly the J/C Y/B that do.

Also this isn't new.

I recall seeing Rogue fares that had cheap TATL one-ways...for destinations that WS flies to.

Purely coincidence.;)

Where "this" is anti-competitive behaviour that has evaporated domestically/transborder but not internationally.

Add Egyptair and Aer Lingus to the list of carriers that I have found great one way fares from (at least for J class departing from Toronto)
