I HAVE read the sticky and as I understand it, I can change my RTW ticket for a change fee + a reissue fee. It is showing as booking class M not L though??

Anyway, the question really is simple. Current routing is LHR-HKG-SYD-CHC-ZQN-AKL-HNL-LAX-LHR.

We have booked a hotel in Hawaii, but on Maui and not on the island where Honolulu airport is. Originally, my wife assumed we'd be able to independently buy our own hawaiian airlines ticket over to Kahului airport and keep our original itinerary. However, she misread our itinerary, and we're on the 07:15AM departure from Honolulu -it seems to be impossible to get there in time on that morning from Kahului. My question is what is the best course of action -is it better to ask whether they can change the HNL-LAX sector to a 'surface' sector, making our own way over to Kahului and then on to LA, or is it best to see if we can get a surface Honolulu Kahului put in and ticket changed to go direct Kahului to LAX -the latter would be preferable as it would save us the money of purchasing a ticket from Kahului to LAX. Even better, is it possible to get added in Honolulu to Kahului and then Kahului to LAX as part of the ticket?? Any idea in the UK what the change conditions on this ticket would be, or if we're totally screwed.

My wife is going in to see the TA tomorrow (I'm on business in Tokyo ATM) -the TA is as clueless as me about this, and he is using a consolidator agent to book the rtw tickets so it's sort of me speaking to wife, wife speaking to TA, TA speaking to his TA and them speaking to OW.

Thanks in advance, I find it quite hard to get my head around!

Edit to add -departing on 19th if that helps, and having a stop in LAX for one night.
