The mass shooting at the end of June saw 33 Tui customers killed following an attack on a beach near the resort of Sousse. The company launched a massive airlift operation to bring home customers still in Tunisia and subsequently cancelled all holidays to the country.

The impact of the tragedy will largely be as a result of the cost of running under-occupied hotels in Tunisia with an estimated figure of €35-€40 million.

“Despite this impact we have tightened our guidance to 12.5 to 15% so effectively what we’re saying is we are absorbing the impact of this cost,” he said on a conference call.

Long said Tui continues to rely on government advice in relation to Tunisia but says it will think carefully before deciding whether to send customers back to the country.

“We are continuing to remain in dialogue with the Tunisian authorities to understand what they are doing and clearly as the situation improves that will make us feel better but ultimately we will not make a decision regarding the recommencing of our programmes until the Foreign Office advice is lifted and they are saying it is safe to travel again.

“And then to be quite frank there will be a combination of our thoughts about that and most specifically what our customers are telling us in terms of their desire to go to the country.”
