Multiple airlines on one ticket - what happens with luggage?

[Omarko_man]

hi

I hope I posted this in the right section.

We have booked a flight from Sydney to Istanbul for a family trip in few weeks time.

I was looking at the itinerary and realised that it has different airlines for the various flights involved to get to Istanbul from Sydney.

Sydney -> Kuala Lumpur - Malaysia Airlines
3hr layover
Kuala Lumpur -> Istanbul - Turkish Airlines

return trip
Istanbul -> Jakarta - Turkish Airlines
3hr layover
Jakarta -> Sydney - Qantas

This was booked as one itinerary through Aunt Betty and flights are in business class if that makes any difference.

Can someone please help us understand what this means for our luggage ?

When checking in Sydney, will they be able to check us on both flights to Istanbul and have our luggage go directly there?

OR

When we get to Kuala Lumpur we need to leave the terminal, go through customs, collect our luggage, go to correct departure terminal for the Turkish Airline flight, check in luggage, go through security, customs etc to get back in ?

the 2nd alternative sounds crazy if that is the case and will no doubt cause us stress as we never travelled this way. If it is the case though, any tips on how to handle this at the KL airport ? where to go ? is their customs process easy ? do we need Visa as leaving terminal means we are entering country etc etc.

Same question goes for our return trip.

Thank you in advance for your input.

If it's one ticket, they will check through and you stay air side (transit) at KUL.

yes, when I look at the itinerary, its the same eTicket number for flight from SYD-KL as KL-IST
