There are many air routes between Ireland's airports and Kansas / Oklahoma - some include direct flights from an Irish airport to a US gateway airport with onward connecting flights, and others connect through European gateway airports (including London).
Many USA gateway airports connect easily to Oklahoma City (OKC) and to Tulsa (TUL) with one flight.
Citizens of the Republic of Ireland are eligible to participate in the ESTA (Electronic System of Travel Authorisation) programme (part of the visa waiver scheme) and may stay in the USA for a period of up to 90 days when travelling for tourism (not work or business) without an entry visa. For the full information and to apply for ESTA, visit https://ie.usembassy.gov/visas/visa-waiver-program/
When researching, planning and booking your leisure trip to the Heartland States - whether it be to visit friends or family, enjoy a fly drive road trip or pursue a favourite activity such as horse riding - there is no substitute for engaging the advice and assistance of an experienced and expert travel provider. We strongly recommend that you consult a reputable travel agent or operator at an early stage in your planning. We work closely with a number of travel partners in Ireland, and you can contact them from Book Your Holiday page.
