Hainan now on sale. DUB-PEK can be booked only on days 26. PEK-DUB can be booked days 2467. EDI-PEK bookable days 47. PEK-EDI bookable 2467. So it appears only the non stop options can be booked Eastbound. Is this due to issues with the CTA/Customs & immigration and not being able to mix inbound/outbound pax?
