I read on https://www.flypointyend.com/5th-freedom-flights/ (mirror):

The fifth freedom allows an airline to carry revenue traffic between foreign countries as a part of services connecting the airline's own country. Fifth Freedom flights are often heavily discounted and it is prudent to keep abreast of the current 5th Freedom routes.

Is it true that fifth freedom flights more often discounted than regular flights?

I haven't seen any such evidence myself and I see other people wondering the same, e.g.:

Do you have some data points that support the claim that these are actually cheaper? I've read about a few times but I was never able to found a fare where the "5th freedom" was actually the cheapest option. – Hilmar 7 hours ago

    Might this get better answers on travel.SE, where they can give anecdotes rather than referenced answers to empirical data?

  • If someone doesn't feel inclined to click on the proprietary (spammy?) link to find out WTF it is talking about, here's more mainstream press article about it: eu.usatoday.com/story/travel/airline-news/2020/02/23/… Commented Dec 27, 2020 at 10:04
  • N.B. it seems a complicated issue because of frequent flyer status: "Frequent flier seats are often easier to come by on fifth-freedom flights than on local lines. Conversely, fares on fifth-freedom flights are sometimes (but not always) lower than local-line fares, which you might be more loyal to." Commented Dec 27, 2020 at 10:11

    Anecdotal: in 2019 I flew KIX–TPE return. I ended up using CX, a 5th freedom carrier, but they were not the cheapest option (I chose them for being in the OneWorld alliance). In fact, I could have saved ¥10k–20k by going for an LCC or even a non-LCC legacy. Unfortunately, the data can’t currently be compiled because neither Japan nor Taiwan are letting foreigners in easily and practically all international flights to KIX have been cancelled.

This statement may have been true before the rise of low-cost carriers, and indeed, in the 2000s I occasionally caught cheap fifth-freedom fares like SIN-HKG on United or KUL-CGK on KLM that were cheaper than the big boys (SQ/CX and MH/GA respectively).

These days, though, low-cost carriers that cut costs to the bone and make up for it with ancillaries (checked bags, meals, seat selection etc) can offer much lower no-frills fares when booked in advance: Air Asia, Lion etc are now by far the cheapest options for KUL-CGK, while Scoot and HK Express rule SIN-HKG. Fifth-freedom carriers can't really compete in price alone, and with new planes making longer point-to-point flights feasible many of these old segments have been dropped.

Edit: I know Skeptics.SE likes references, but historical fare data is kept under lock and key and flight schedules & pricing are currently messed up by COVID. The overall ascent of LCCs and decline of fifth freedom flights is well known though, see eg this article from industry analyst Sam Chui:

Until 2017, United Airlines operated several fifth freedom flights from the United States to cities like Hong Kong and Singapore via their Tokyo-Narita hub. However, a new generation of twin-engine, fuel efficient and long-range aircraft, like the Boeing 787 and Airbus A350, have made such intra-Asia flights obsolete. In 2017, United Airlines began a nonstop service between San Francisco and Singapore on their 787-9 aircraft. Doing so, ended their historic fifth freedom service between Hong Kong and Singapore.

  • This still needs references: "low-cost carriers [...] can offer much lower no-frills fares when booked in advance" Says who? "Air Asia, Lion etc are now by far the cheapest options" Says who? "many of these old segments have been dropped" Says who? Please remove the claims you assert without substantiating.

  • @Oddthinking This Q is in the wrong SE, please move it to Aviation or Travel. Commented Dec 29, 2020 at 10:03
  • I don't hink it is on topic at Aviation. It's already on Travel so migrating will just get it closed as a dupe.

    @Oddthinking The question here is "whether" they're cheaper, the question on Travel.SE is "why" they're cheaper. <shrug/> Commented Dec 29, 2020 at 10:53
