I have booked as follows for early December, late morning/early afternoon, hand luggage only, no seat selection:
* HND-NGS, ANA (Operated by SolaSeed) SUPER VALUE 28L,17200JPY (85 UKP)
* FUK-HND, StarFlyer SORATABI 28, 12,680JPY (64 UKP)
Could have got cheaper flights if I was travelling early morning/evening.
SkyMark online booking was inaccessible using my browser(s). Some error about the security certificate.
One thing that confused me about the online booking process was the distinct Confirmation and Payment stages.
I have paid for both flights up front, and completed the purchases. Do I also need to Confirm my flight online, nearer the departure time? Probably not, I think.
