I toured four planes in Gulfstream's corporate fleet and was shocked at how luxurious the experience was for people who regularly fly on the planes

• Gulfstream has a fleet of corporate jets, which include spacious cabins, luxurious galleys, and shower space.
• The planes range in price from $25 million to $78 million.

Gulfstream has seven jets in its portfolio. While some are still to enter service, others have already amassed thousands of miles flying people around the world.

I toured some of the Gulfstream demonstration planes while they were on display at the European Business and Aviation Convention and Exhibition in Geneva.

The G280 is the smallest of the Gulfstream fleet and the least expensive, with a price tag of $24.5 million.

Inside the main cabin of the model I boarded, there were ten leather seats with added tables, charging plugs, and drink holders. The cabins are customizable and can be reconfigured in any way, according to Gulfstream.

With two living areas, the plane can accommodate up to ten people and sleep up to five.

The jet has a camera fitted on the outside and has "steep approach" capabilities, according to one of the pilots onboard.

That means the aircraft can take off from airports like London City Airport, which is surrounded by buildings, and quickly climb to its cruising altitude of 41,000 feet.

The aircraft can travel up to 3,600 nautical miles. It has a "ton of power," for its size according to one of the Gulfstream pilots. "It's like flying a little sports car," the pilot added.

There are more than 200 of the Gulfstream G280s in operation. The model is often used by charter companies, but a large proportion of the smaller planes currently in operation also belong to private individuals and families, according to Gulfstream.

The Gulfstream G600 is larger, faster, and more spacious on the inside.

The cabin was configured in the same way as the G280 I boarded, but can hold up to 13 people. Large windows in the cabin space let lots of natural light in.

The cabin space also has an additional living space, with a fold-out divan. It can sleep up to six people.

Similarly to the G280, the G600 is used by both corporate customers who purchase the planes for their fleet and private individuals. Gulfstream has seen "great demand" from charter companies for the model in recent years, according to one pilot.

The jet can travel up to 6,600 nautical miles and can be used to link cities like New York and Dubai, and London and Beijing non-stop, according to Gulfstream.

The G650ER felt more spacious but can accommodate the same number of passengers in the same number of living spaces as the G600.

The configuration of the G650ER model I boarded was slightly different, with a large, fold-out screen in one of the living areas.

The model also had space for a fold-out divan, plush chairs, and entertainment screens dotted around the plane.

Like the other models, the G650ER had a long galley with a sink and storage facilities.

The G650ER is one of two models which make up Gulfstream's G650 range, with the other model being the G650. According to one of the Gulfstream pilots, the only difference between the two models is fuel capacity.

The Gulfstream G650ER can travel for around two hours longer than the G650, and can fly for around 15 hours non-stop, a Gulfstream pilot told Insider.

The final model I saw was the Gulfstream G700. The model was the largest and the most expensive of the Gulfstream jets on display, with a price tag of $78 million. The model is still in test mode, so the plane I boarded was the only G700 model in Gulfstream's current fleet with the cabin fitted out.

The cabin space is longer than the other Gulfstream jets, with an extra ten feet and one inch of living space. The plane has four living spaces, which can hold up to 19 people and sleep 13.

The aircraft also had a private room with a pull-out divan and an additional seat pair.

The seats on the G700 can recline into beds but the cabin is spacious enough for a client to choose to have a full-size bed installed.

The G700 can also accommodate a shower but the model I visited didn't have one onboard.

The jet also features an entertainment screen in the main cabin and cabin controls situated at each seat to control features like cabin lighting and window shades.

The G700 also features a longer galley than the previous aircraft, where kitchen amenities can be found.

The G700 can travel as far as 7,500 nautical miles, taking passengers on flights as long as 14 or 15 hours.
