Shanghai Airlines

Paid extra $300 for the upgrade. Cabin small and private, cabin crew very helpful, and bathrooms kept very clean.
All subsequent flights with this airline/China eastern were boarded early, left early, and arrived earlier.
Crew gave a person on our tour a cake and card as it was his birthday which was a very nice touch.

I am glad this was a short flight of 3 hours from Shanghai to Harbin in a B737-800. The flight was full and cramped. The breakfast meal service was the worst food I have had on an airliner in a long time. Meal service is the standard haphazard level of the parent company China Eastern with the croissant arriving a long time after the meal. Incidentally the croissant was the only edible part of the meal. Coffee comes with milk and sugar already added so if you prefer coffee black without sugar, tough!!
I would not fly with this airline again!
