A carriage?  Tinnun doesn't normally ride those, as she often travels by foot and wing.  Mostly this is owing that such transportation only go to nearby towns, not to a completely different region.  A bit hazardous, yes, but she knows how to get off the ground and fly away if she has to run away.

Seeing Krysanthia signal to go ahead in the carriage, Tinnun entered it.  It was a bit easy for her to fit in, being a fairly petite bird lady.  She thought that the bag in which she carried the things the Rito needed for cooking would be more difficult to fit in, but apparently not.
