Thought you might be interested in the most unusual flight I ever took. It's a little short on technical detail, but I hope you still enjoy the info.

Flight from Singapore Changi to Christmas Island.

Plane - Boeing 737
Airline - It had an MAS badge on the tail, but that was the only way of identifying it. See below for description of the inside.
Flight time - 1 hour 40 minutes.

This was a special flight, taking various business people to Christmas Island for a media announcement. I arrived at Changi Terminal One for check-in. There was just one specially designated desk for the 15 or so people taking this flight. After checking in, we were escorted straight to the departure gate. Walking past the flight departure screens I could see our flight had been designated XX 1.

From the departure lounge I could see that the only markings on the place were an MAS tail badge.No other markings.

Inside it was more like a private jet. The front third was normal airline seating, albeit very plush and with economy-plus leg-room. The rear two thirds, though were amazing. Three sets of four huge, leather seats around big tables (the seats facing front and rear). Also two huge sofas, with deep shag-pile carpet. A small bar area. In the rear, 2 washrooms, with gold plating everywhere.

We took off at around 7pm for the short flight to Christmas Island. Looking after the passengers were 4 flight staff in some kind of uniform...not normal MAS. Shortly after take-off we were offered drinks. I had a scotch and soda in a huge crystal tumbler. Dinner was then served. Three fantastic courses, without doubt the best food I've had in the air.

We arrived at Christmas Island after dark, so couldn't see anything outside. When we touched down, the only other plane there was a Royal Australian Air Force VC10 (I think).

The terminal building was small, and a simple functional concrete block

On the return journey the next day, the pilot circled at low level (I'd estimate around 3000feet) around the Island shortly after take-off so we could have a close look at what we'd already seen from the ground (the proposed site of a satellite launch pad).

It was a great flight on an unusual plane to an unusual location. I was told the plane is meant to be used by the Malaysian Government, but it can be leased for private use.
