There are various types of transportation vehicles in the world of Hunter × Hunter.
Airships are a type of aircraft widely used for long distance travel. They are spacious enough to include bars, lounges and bedrooms. The first airship seen in the series was used by Chairman Netero when he visited the participants of the 287th Hunter Exam during the 2nd phase. Ringon Airport in Yorknew City seemed to have only airships.
Another type of aircraft that has been seen in the series is hot air balloon. The Phantom Troupe used a hot air balloon to escape to the Gordeau Desert after raiding the Underground Auction. Milluki Zoldyck used a small hot air balloon to leave Kukuroo Mountain to go to Yorknew City.
Due to the world in Hunter × Hunter is being limited by the Dark Continent, the necessary to develop airplane is unnecessary due to the short distance between countries in the human world. However, it is also strange that short range aircraft like helicopter is not seen or being developed.
In the preliminary phase of the 287th Hunter Examination, Gon, Kurapika and Leorio went to Zaban City on a ship. In the 4th Phase, the candidates had to use some boats to get to Zevil Island. The Phantom Troupe used a boat to reach Greed Island as well.
Cars are the most used transportation vehicle. Leorio once had to drive a car to help Kurapika go after the Phantom Troupe. During the Southernpiece Auction's time, Neon's bodyguards were shown to have several cars of their own. Aside from private cars, vehicles for hire such as taxicabs and buses are also popular. In the Republic of Padokea, Gon, Kurapika and Leorio took a tour bus to reach Kukuroo Mountain. During Killua journey to save Gon, he and his butlers are seen using a limo as mean of transportation. Bizeff, Hina and Welfin are seen using an RV to go to Meteor City to find Gyro.
Transportation vehicles like truck are used heavily in the Republic of East Gorteau to transport items to the basement of the Palace.
Rail vehicles are a common type of transportation. The first train seen was the one on which Gon, Kurapika and Leorio got to the neighborhood of Kukuroo Mountain. In the 1999 anime, Kurapika meets Melody in a train station. The Phantom Troupe rode a train when chasing after Kurapika. Morel Mackernasey and his comrades took a train to arrive in the Republic of East Gorteau during their Extermination Mission. Only the names of a few stations have been known are Kastour, Lipa and Tarsetol Stations. Gon and Killua rode a train to meet Kurapika at the beginning of the Hunter × Hunter: Phantom Rouge movie.
