The online exchange feature works very well IME despite all the constant bashing of it here. I have successfully used it at least a dozen times. To delete just one segment, at the bottom you can click "more options" which will bring up buttons for "delete segment". You can use this for example to completely change your itinerary by adding new future segments and deleting all your current segments one by one. You then have a completely different future itinerary (to different cities even if you wanted) that will price correctly, and if you confirm it will charge your credit card appropriately and give you a new e-ticket number. The only thing you can't do is select seats. There is also a limitation on the number of "exchanged" tickets it will process... so if your ticket has already been exchanged in the past (I think the limit is 3 times), it may not work. That is the only time I have run into problems with it.

While everyone trashes this, it has pretty much always worked for me (except for the multi-exchange issue above), and works better than the similar NW feature and surely better than the non-existent AA feature. WN is the best at this hands down. Have faith brothers... it does work!
