The rules state the following:

In January or February of this year I successfully changed the first flight on a DONE4. AA insisted it wasn't possible but I insisted they direct me to the relevant section of the technical rule sheet for the oneworld explorer fare. They couldn't.

Strange, since AA showed me the relevant section without hesitation. It is in their rule sheet, in CX's rule sheet and in BA's rule sheet. Guess you lucked out.

Of course if you change the flight within a period where there is no price increase the reissue against current prices does not make any difference.

Or lucked in.

When I made the change I had a thorough look at the technical rule sheet and didn't see a rule prohibiting such a change. Admittedly, it the change was only delaying travel by one day on one flight but still a change nonetheless.

Trust me, it is there. There are two rule sheets by the way. The one published on the OneWorld website and the one by the issuing airline. The latter states the reissue first segment situation.

To illustrate: when CX made me miss my first flight of an DONE5 they had to reissue themselves against the new rate and reimburse me for the difference in order to stick to IATA rules. Silly, but true. (Money never changed hands, but my ticket does have the new price etc).

AA reissued a DONEx ticket without charge for me when CX cancelled the first flight. The AA agent noted that the reissue was due to a schedule change and didn't even have to go through the tariff desk.

Okay, I trust you. However, I don't believe it was in the rules (or at least explicitly clear) when I made my change earlier this year.

It has always been there as far as I know. Obviously the rule only kicks in when there actually is a price difference. Maybe if the difference is not so substantial they don't charge you? In my case the price difference was over $800,-.

And again: it is not in the ruile sheet on OW but the specific sheet from the airline. I posted a link to one in an earlier reply (#14) to this topic.

I have recently changed the departure date of a Aone4. The ticket WAS reissued but NOT repriced. I did not change the routing.

Was there a price difference?

If there was, I don't know what to tell you. The rules are clear but clearly not alwasy applied. The link to the rule sheet is in reply 14.

No change in price. I did the same with another Aone4 last year no change in price.

Here is the rule sheet:

If there has been no change to the fares , then a repricing will just reprice the same as before so no impact; does't provide anything substantive to the repricing on a rebooking of the 1st flight

Who issued the ticket originally, and who reissued it? AA RTW desk both times?

When you say "No change in price" do you mean no change in price to you (that is, no re-price), or that the itinerary priced the same (that is, you could purchase the same itinerary at the same price on the date of the change)?

Once again: not that one, but the one in reply #14.

And I indeed meant was there a difference in price between the day you originally bought the ticket and the time you made the change to the first flight (e.g. was there a published price increase)?
