It's my first time flying with Alaska Airlines. All in all it was very good. Excellent crew and the meal was really good .. best mashed potato!! Black point: not waking me up for breakfast. Having departed late from London and arriving in Seattle late at night, it would have been nice to have found a meal on the table when i woke up. Although the crew was very lovely, kind and helpful, I did find it a little regimented in their approach. Also the constant interruptions announcing what we were eating next and unnecessary announcements.
