The majority of tourists arrive at either of Sofia’s two airport terminals, although in summer many fly directly to the coastal cities of Varna and Burgas on charter flights. Frequent low-cost flights from London and other European cities to Sofia, are provided by easyJet and Wizz Air, which also has summer services to Varna and Burgas. The national carrier Bulgaria Air (wwww.air.bg) serves most of Europe but there are no direct flights to or from North America or Australasia.
Bulgaria has land borders with five countries and reliable international rail links. Popular routes include from Bucharest to Veliko Tarnovo (5–6hr) or to Sofia (11hr), and from Thessaloniki to Sofia (10hr), while trains from İstanbul traverse the country, stopping at Plovdiv (11hr) and Sofia (14hr) before continuing to Belgrade. Eurolines (wwww.eurolines.bg) runs frequent bus services to Sofia from many major European cities and has booking offices in Sofia, Plovdiv, Varna, and Burgas.
