Travel operator Tui has warned it will take a €200 million (£172m) hit from the grounding of Boeing 737 Max planes.

The firm said the impact is attributed to costs for replacement aircraft, higher fuel charges, disruption and the anticipated impact on trading.

As a result, Tui has downgraded its profit guidance and now expects underlying earnings to be down 17 per cent on last year's €1.18 billion (£1bn), it said.

This compares to previous forecasts of flat earnings.
Tui shares collapsed nearly 10% to 700.4p following the announcement.

The firm said it has made arrangements in order to "guarantee customers' holidays" by utilising spare aircraft in its fleet, extending expiring leases for planes that were supposed to be replaced by the 737 Max aircraft, as well as leasing in additional aircraft.

The travel giant also warned that should it not become clear within the coming weeks that flying the 737 Max will resume by mid-July, Tui will need to extend the measures until the end of the summer season.
