Prices on these flights can fluctuate from time to time due to inflation but, depending on the airline, are usually between USD125-132 return from and to Port-au-Prince, cheaper between Port-au-Prince and Jacmel. A really cheap, dependable and popular airline is Sunrise Airways
There is a regional airport in Jacmel, but it doesn't have a regular flight schedule.
Airlines that fly to Haiti
flies from Fort Lauderdale and Miami to Cap-Haïtien. MFI Missionary Flights International fly to Cap also from Florida, but only registered non-Catholic Christian missionaries are welcome aboard. Other international airlines serving Cap-Haïtien include Sky King, Turks and Caicos Air and Pine-apple Air.
From Santo Domingo, Caribe Tours runs a once-daily bus to Petionville in the hills above Port-au-Prince that leaves at 11:00. A ticket costs USD40 one-way, USD26 tax and and DOP100. Unfortunately, this bus drops you off in Petionville after dark so make prior arrangements with a trustworthy person to meet you and transport you to your lodging.
There is also a crowded border crossing between Dominican Republic and Haiti in Dajabón/Ouanaminthe. The border is open only during the day. From here you can catch local transport to Cap-Haïtien.
Another, less expensive, option from Santo Domingo to Port-au-Prince, is to take a gua-gua Dominican minibus from Santo Domingo departing a few blocks north of Parque Enriquillo for DOP380 about USD10, 5h and arrive in the border town of Jimani. From there, it is a 4km walk or a DOP50 ride by motoconcho to the border post.
The border is apparently open 09:00-18:00 but don't rely those times. It is very easy to cross the border without submitting to any immigration procedures on either side, and although it would probably be illegal, it saves a few dozen dollars on bribes and is much faster too. Apart from entering the DR when a soldier takes a look at the passport, nobody does any inspection: immigration or customs. Entering Haiti legally is quick: fill out the green form and pay whatever amount the official asks around DOP100. There are no ATMs at the border.
Moneychangers give Haitian gourdes in exchange for Dominican Republic pesos and US dollars. Rates are fair. There is plenty of local transportation from the border to Port-au-Prince. Crowded tap-taps and buses can take you to Croix-des-Bouquets for HTG50 1.5-2h, from where it is another hour to Port-au-Prince proper bus, HTG5. The road has variable conditions and and is prone to flooding. Peruvian UN soldiers at the border have confirmed that the road to Port-au-Prince is safe to travel with no incidents of robbery or kidnappings, but definitely try to arrive in Port-au-Prince before dark.
