Top Deck of 747s
 

Is there still an airline anywhere that does not use the top deck of its 747s for regular passenger seating but reserves the top deck for a lounge?

None that I know of. In today's age of $70/barrel oil, it just doesn't make sense.

I have very good memories of some airlines using a lounge in their 747. Some even had a chef, tables like in a restaurant...it will be interesting to see the A380 and their F cabin. I would mind paying a premium providing it is really F class (lounge, caviar, Dom, etc...)

No airline used the top deck for a lounge after the SUD (stretched upper deck) was introduced. All of the non-SUD 747s have been scrapped by now. The original 747 had space for only 4 seats upstairs, thus the desire to use it as a lounge instead. I think one airline used it as crew quarters, not for pax use. This was before they got the crew quarters in the tail on the later 747 designs.

I think there a few still flying - Orient Thai springs to mind as one operator and I have a feeling JAL still have a couple. Plenty of -200 Freighters left out there too.

1. There are still some non-SUD 747s flying for JAL and NW and (I believe) ANA.

2. The classic 747s have room for way more than 4 seats upstairs. More like 30-40 coach seats or (in the case of NW) 12 first class seats (now sold as business class) at 70 inches of pitch.

Not quite. There are still a few passenger 747-200s that come through London Heathrow regularly on scheduled flights, Iran Air and Pakistan International can be seen often, also Syrianair 747SPs that have the same upper deck arrangement. They have put business-class seats up top.

The first airline to fully seat the 747 was Canadian charter carrier Wardair, who got their first 747-100 in 1973. They put economy 3+3 seating up there, about 24 seats (4 rows) all told.

I've never heard of all-crew seating up there (except on freighters), possibly a misinterpretation of the later crew compartment.

Here is a picture of a fully-Y seated 747 original-size upper deck, in this case an Iran Air 747SP taken a couple of years ago. This aircraft has been through Heathrow in recent times as well. In this case 24 seats are visible, as well as a small galley.

Syrian Airlines
 

Last year I travelled (not by choice) on Syrian Airlines on a 747-SP in First. There was a lounge on the upper deck. First class is in the nose. It was SO retro. Felt like it was 1972 (which I think was the last time the aircraft had been cleaned .. but that's another story). I don't think it has been changed since I flew on it.

Virgin Atlantic??
 

I have heard radio ads in the Washington DC area for the "Diplomat" flight each day from IAD to LHR. I think the ad notes that there is an upper deck lounge, as well as in-flight massage offered. Haven't chedked the Virgin Atlantic website to confirm this however.

Air Force 1?

Afraid the Virgin flight to Washington doesn't even use a 747, but an Airbus A340-600. No upper deck on that at all.

You would mind, or you wouldn't mind?

Communication equip is up there.

Slightly off topic, but I was very disappointed today to learn that AF uses the upper deck for coach CDG-JFK....

I was really looking forward to my first time on an 74's upper deck.

(OK, it was an award ticket for high season picked up 2 weeks before, so I wasn't TOO disappointed, but it would have been nice.)
