Hi everyone.

Not relevant to my own RTW but helping a friend plan one and don't think I've come across anything specifically about this.

Is there any issue with the final segment being a surface segment? For example, DONE4 starting in OSL. Can the last 3 segments just be DFW to DUB on AA, then a surface segment from DUB to OSL? So effectively the final flight is DFW to DUB.

Thanks for any advice.
