Making us check our bags at the gate then finding out there was plenty of space on the plane was annoying. Otherwise a smooth flight that was only delayed by an hour on the first leg and another hour on the second leg due to technical problems. Nice bathrooms for an airplane and nice to set out a self serve station for beverages between service.
