This article (
Skyteam to launch alliance-wide online booking tool) has more on the last two bullet points above:
- An alliance-wide award booking tool means that 'by the end of this year', every SkyTeam FFP will have an online tool that enables award booking on other SkyTeam members, rather than having to phone a call-centre. Apparently, the tool is already in place for ten members (the article doesn't state which ten...)
- It also mentions SkyTransfer, allowing any member airline to access a passenger's PNR and make rebooking in the event of IRROPs.
