All a surface segment means is that you are not flying between the two cities involved as part of the ticket. How you from A to B is your problem, not theirs. Surface segments are a good way to avoid wasting a segment when the distance between the two cities is small and/or the price is cheap.
So, then, I do not need to have a continuous route on a xONEx ticket? For example, I can go HKG-JFK, with my next segment being, for example, LAX-HNL, and the following segment SNA-DFW, and I don't have to get to LAX or later to SNA on the xONEx ticket for it to be a valid routing?
