Hi. something I hope you will enjoy seeing … interestingly I found this while researching this cover

June 4 – Philippine Airlines begins the first transpacific sleeper service, using Douglas DC-6 airliners between San FranciscoCalifornia, and Manila in the Philippine Islands

Seems so  long ago, and still we fly with no sleeper service on some airlines 🙂 

I think I will stay with 777 or A380  🙂    have a great day
