I am travelling from country A to country B. I want to spend about a month in country B and I would like to repeat this journey in 6 months or so.

Are there any rules against buying 2 roundtrip tickets like so: 1) A-B September, return flight B-A May 2) B-A October, return flight A-B June

Then flying to B using the first leg of ticket #1 in September and coming back to A using the first leg of ticket #2 in October. Similar process in May.

    this is called "nested returns" and most people do them on different airlines just in case Aug 28, 2019 at 1:14

    Thank you! I couldn't find figure out the right term to google, now I know :) Aug 28, 2019 at 1:35
  • Note that these are technically not "nested" as in XYYX, but rather "interleaved" as in XYXY. Aug 28, 2019 at 12:30

Nested returns are totally fine and quite common for say, Kiwis who have gone to live in London - 1 way over there, then returns from London to NZ, repeat for x years, then a 1 way back to NZ even.

I've also had LON-EZE return, and inbetween, went EZE to CHC and back, then back to London later.

    Thank you. I wasn't sure because I remember there was something that airlines definitely did not like back in the day. I can't find what it was now but it was something about combining multiple trips Aug 28, 2019 at 1:38

    @NoobTraveller they don't like you buying a return and then only using half of it, or trying to take the second leg of an itinerary, but as long as you take all legs of an itinerary, I've not had problems.

    @Sean on some routes, a return leg is actually cheaper than a one way, so then they really don't like it ;)

    @Sean, nope, not always. Eg from A to B costs $5, but A to B return costs $4. Was with a friend when he bought a ticket like this from Bolivia to NZ, and often comes up in the US. Articles exist on this, eg traveltips.usatoday.com/…

    @Sean a case I personally experienced: one-way HEL–TXL was €500, the return trip HEL–TXL–HEL around €100. Needless to say which I took. (Same airline, same flight ftr.)
