Anyone for a jumbo 747 restaurant or a downstairs cocktail lounge? They were just some of the crazy - and not so crazy ideas - that Boeing and other manufacturers came up with to sell the virtues of new jumbo designs that promised room to move.

Boeing introduced the spacious age with its 747 in 1970 but airline chiefs were initially scratching their heads wondering how to fill all the space as the 747 was more than twice the size of the 707 it would replace.

So the interior designers had a field day with creativity. Here are just some of the ideas. The Tiger Lounge (below) was offered as a downstairs option for the 747.

Access from the main passenger deck was via a staircase. Another variation was to turn the space into a downstairs restaurant. And there was to be a smoking club bar area as well. Boeing also suggested that the nose area of the 747 could be used as a lounge.

Another option was an "Austin Powers" styled lounge - about 20 years before Austin Powers!

About AirlineRatings.com Airlineratings.com was developed to provide everyone in the world a one-stop shop for everything related to airlines, formed by a team of aviation editors, who have forensically researched nearly every airline in the world.

Our rating system is rated from one to seven stars on safety – with seven being the highest ranking. Within each airline, you will find the country of origin, airline code, booking URL and seat map information.

The rating system takes into account a number of different factors related to audits from aviation’s governing bodies, lead associations, as well as the airlines, own safety data. Every airline has a safety rating breakdown so you can see exactly how they rate.

Over 230 of the airlines on the site that carry 99 per cent of the world’s passengers have a product rating. Given that low-cost, regional and full-service carriers are so different we have constructed a different rating system for each which can be found within each airline.
