Iberia: Granada-Barcelona- Singapore ?Baggage

Subscribe
Can anyone help me confirm if my luggage will be checked straight through from Granada to Singapore?

I am thinking of flying from Granada- Barcelona by Iberia Airlines.
Then from Barcelona- Singapore by Singapore airlines
There is a 2 hour lay over at Barcelona and am not sure if it sufficient time, especially if I have to reclaim my luggage at Barcelona and re-check in.

Thanks for your help in advance

Welcome to FlyerTalk.

The main issue is whether IB and SQ have an interline baggage agreement (I believe they do, and have seen it stated by some on the Internet,) in which case you should be able to check your baggage through.

Another query:

If the flight from Granada to Barcelona is operated by Vueling airlines (but has Iberia code), does the interline baggage agreement still hold true?

Thank you
