My recent trip to India was flown in the comfort of Delta’s business class cabin. The lay-flat seats with Westin Heavenly Bed pillows and blankets are to die for! The food is good, and the service phenomenal. My friends at the blog: OneMileAtATime do a terrific job critiquing the airlines, so I refer you to their site. The connection to Amsterdam was to a KLM business class cabin. Small seats, did not lay flat, old entertainment system inattentive crew. Recommend Delta, not so much KLM.
