Delta has upped their game - everything - food, drinks, baggage... no additional cost. Great in-flight service - example... prior to meal delivery everyone was handed a warm wet hand-washing towel. Best flying experience in years.

We were in economy coach (BASIC) seating but treated and served by the flight attendants in an exceptional manner. Also, appreciated the new PDX to LHR direct flight. We will definitely fly Delta again.
