Checking in took way too long. A 30 minutes delay on a morning flight isn't great. Ok it was a Monday morning and extra staff could (and should) have been deployed. The flight was good, the staff was helpful and friendly. Retrieving the luggage at Hobart should have been easy. A very long way for our luggage was how our patience has been rewarded.
