Any Airlines with Open ended tickets where Return can be determined later by design, or without a change fee?

Question

Sometimes when I do extended travel I have no idea when I will be doing a return and would prefer to choose the return segment later.

• Not looking for Full Fare tickets {no change fee} or First class
• One ways (usually more expensive) than Return fare

Examples:

• I remember almost a decade back, a friend traveled India <> US via AI and had an open ended return ticket; he did not have to choose a return date/ hence no change fee to select his return.

• Apparently, a similar example was posted here about JAL.
  Is there a way to check that the conditions on your plane ticket are actually what your travel agent said they are?

• Related Q&A: What is the best method of purchasing a ticket with an open return date?

Some history and information on Travel SE:

• No more open returns?

  True open return tickets faded into obscurity last decade, my cobweb filled brain wants to say 2008 or 2009.

  Open return tickets have faded away but they still exist in some airlines.

Which airlines still offer this now in 2015?

Please answer/ list airlines that you know still offer this, maybe directly, online or via travel agents.

Answer 1

Few airlines still sell open return tickets (that do not require reservations to be made). The exception is round-the-world and visit-a-continent fares which do still allow this.

However, virtually all of them sell changeable tickets that can be changed at any time. On the flip side it may not be cheap.

That said the ticket validity is usually limited to one year after date of purchase.
