TUI AG (TUI1) Chief Executive Officer Michael Frenzel said concern about extra charges for travel to Greece this summer in the event of a currency change in the country are unfounded, Bild Zeitung reported.

Tour operators negotiate hotel prices and air fares a year ahead, Frenzel told the newspaper.

He advised travellers to bring extra cash in case Greek ATMs aren’t functioning, Bild said.
