Where is gate C29? Is it on a different floor? And if I check in online do I just go there and to my terminal or do I still approach someone at a desk? Feedback would be great lol

You still have to check a luggage, @ the desk, if u have one.. Go through security, then follow, signs that tell u where, the gate is.

There is a secret terminal where c29 is. Follow signs for gate E and you will see an entrance for gate Z hidden between E14 and E15. Descend the stairs. Then you come to the desk. Then you descend deeper. There you find c29

The 4th terminal would be terminal D

Okay cool and as for terminal 4 where is that?
