I'm currently in CPT making my way back to NCL via IST and DUS. I'm on an LH-issued award ticket. Two flights on Turkish, with the final leg being on Eurowings.

At check in, my bags are tagged all the way to NCL though Turkish say they can't issue a boarding pass for my Eurowings flight.

On the Eurowings app, it says it's Turkish's responsibility to issue the boarding pass.

I have a very short 45-minute layover in DUS.

What will happen when I rock up to the gate in DUS without a boarding pass? Will there be an issue?
