My husband has just flown 4 consecutive nights on planes. I had the time for a more leisurely start to our trip, so I've only had two consecutive nights. What is your record?

His routing:

Night 1: LAX-HKG, CX - flight delayed from midnight to 5am due to mechanical problems. Had 12 hour layover in HKG; met a friend and went sightseeing.

Night 2: HKG-JNB, CX - old first class configuration. 13 hour layover in JNB (with me); slept, worked out, and shopped for ostrich products.

Night 3: JNB-LHR, BA - 6 hour layover, used Arrivals Lounge and Concorde Lounge, then flew LHR-DXB

Night 4: DXB-LHR, BA - 4 hour layover before our flight to HEL and the true start of our vacation, enjoying the white nights of northern Europe.

Anyone flying in coach for 4 nights way out trumps this trip!
