Our friends have AONE3 issued and started in Korea and we are now in half way (Asia-> Europe->USA).
Since I have AONE4 including South America, my friends want to change their tickets, and go to South America with me, so their tickets have to be reissued as AONE4, from AONE3.

Now, we realized the price from Korea went up.
Do they still pay only reissue fee, the original price difference of AONE3 and AONE4, and taxes?

or do they have to pay the difference of original AONE3 and new AONE4 price which is significantly higher than original AONE4.

Thanks in advance.

Based on my memory of a post from a while ago (and I can't remember where to find it), I believe that the new tix will be priced at current prices and you'll have to pay the difference between what you paid and the current cost of the new tix plus change fee. If I'm wrong, though, I'd love to hear it because I might like to do the same thing. Anyone with better info?

I changed a DONE4 to a DONE5 a year ago and the price was the one current as of the original issue date.

This actually makes a difference to me, as I said above. Just called the AA RTW desk, where I originally booked and bought. The agent first said that I'd have to pay up to the current price, then said that I would only have to pay to the AONE4 price in effect at the time of purchase, then said that he wasn't sure, so he would call the tariff desk.

Answer is that you have to pay up to today's fare at the point of original purchase. So, I'd have to pay the difference from the sale price AONE3 to today's AONE4, both ex-ICN. Yuck.

Looks like I'll use as much of the current ticket as gets me to LHR, then LHR-HKG-ICN will expire unused (e-ticket), and I'll have to buy one way LHR-JNB.

I'm very open to a better approach, if someone has one. Thanks in advance.

xONEx rules are unclear about this:

IMO they will ask you to pay the current price at origin. The ticket is recalculated at the moment you ask to add one more continent. This implies that the price valid at the moment of the recalculation will be charged (i.e. the higher price). However, this is only my interpretation of the rules above. I have no experience other than reissue without increasing the number of continents.

I guess it depends on the agent you talk to at AA.
I changed a ticket from an AONE4 to an Aone 5 last year. I paid the fare difference between the 4 and 5 at the price at the time of the original ticket issue. HOWEVER if I was to change the ticket I purchased during the 10% off sale from an AONE4 to an AONE5. I would pay the difference in fare of the AONE4-AONE5 at NON SALE price. OW considers the price BEFORE the discount as THEE fare the 10% discount was not part of the BASE fare.

Thank you so much for the information.

If I give up South America and change from AONE4 to AONE 3, I know there is no refund, but the current rate of AONE3 is more expensive than original AONE4, do I have to pay the diffrence or just change it with no refund?

I would call the airline that issued the ticket. I believe you may get the taxes you paid on the segments you bypassed refunded. Other than that you should just have to pay the $150 reissue fee for the reroute not the price of a new ticket. I am NOT an expert.

I phoned the AA RTW desk about this not long ago, and was told that the although the fare difference when re-issuing from an xONEx to an xONE(x-1) is not refundable, it�s value can be used towards payment of other charges as part of the same transaction... this includes not only the reissue fee (which is still $125, I believe), but also things such as extra taxes (if any), and even the surcharges for WTP/PE (in case it was an LONEx in the first place).

As I�ll soon be making such a transaction myself, I�ll let you know how it really pans out, but the above position seems to fit with all reasonable expectation: as the residual value from regular non-refundable fares can often still be used towards the purchase of other tickets, such should be the case for xONEx fares as well. Non-refundable just means non-refundable, (rather than totally forfeited, as the some have suggested here).

Last time i added a continent to an AONE the price was calculated:
Original Price for AONE4 at time of ticket issue in the local currency minus original price (paid for the ticket) in the local currency.
Difference multiplied with current exchange rate into the currency the ticket was issued in.
I am not aware of any changes to the rules. This was on CX stock and all done by my travel agent.

You could fly to ICN as planned and then do ICN-HKG-JNB?

So, to make sure I understand, if I want to convert an AONE3 ex-ICN to an AONE4, you're saying that the price is calculated as follows: (AONE4 price ex-ICN when original AONE3 was issued) - (actual price paid for AONE3) converted into the local currency of this new transaction. Have I got it?

OK, now, I bought the AONE3 during the 10% off sale. How does that play into this? Is the price for my new AONE4 based on the sale price or the ex-ICN price which would have been in effect but for the sale?


Well I don't actually want to go to JNB. I believe that it is currently the least costly place to purchase an AONEx ticket, as it was previously, so I wanted to get back there to buy my next ticket. Given the recent price increases, however, I may be switching to SQ for the FEZSQ fare, a full USD$2,000 less than the AONE3 (or AONE4, if purchased in JNB). Although the FEZSQ is significantly more restrictive than an AONE3, it does meet my needs.
