ABTA has met up with airline representatives in an attempt to avoid any problems caused by the demise of paper air tickets at the end of May.

IATA has banned paper tickets from May 31, insisting only electronic tickets be issued, although these still cannot be used on 4% of ex-UK flights.

Trade relations manager Susan Parsons said: “Agents will only use airlines that can issue e-tickets. Carriers that don’t communicate could lose out because agents won’t use them.”

Interline tickets have caused most concern, prompting Advantage to call for a six-month delay.

However, the global distribution systems said agents can issue virtual Miscellaneous Charge Orders where an airline or route cannot be e-ticketed, allowing passengers to collect their ticket at the airport.
