Just because a handful of airlines might tell you that PNRs can be "linked" in various ways ("linking" different passengers on different PNRs but on the same flight(s) is a very different thing from "linking" different/successive PNRs for the same passenger on different airlines) does NOT mean that this is an industry-wide standard.

"Linking" PNRs is very much the exception, not the rule.

I don't know if you tried to purchase all these flights in a single transaction - the only standard way to "link" travel on different airlines - it's not always possible to do so.

But there certainly is no way to "link" these separately issued tickets on these 2 airlines who have absolutely no cooperation now that you have had 2 separate tickets issued.

If you fail to turn up on time for your second ticket - even if, through no fault of your own, such as due to the late arrival.of your first ticket's flights - you bear all the responsibility for missing your flights; your second ticket will (most likely) already have been cancelled due to your no-show.


When you can't issue all travel on a single ticket, then you need to plan pessimistically and allow sufficient time between both tickets so that you have the greatest chance possible of making your connection, even in case of delay or disruption (which it sounds like uou have done by allowing 6 hours. I have a lower tolerance for risk, though, and would usually arrive the night before a longhaul ticket departs). Also bear in mind you usually will not be able to check your luggage through from your first to your second ticket, so count on having to wait for baggage reclaim and having to re-chevk bags at the destination of your first ticket.
