Are Thomsonfly changing flights???

Hi

Just been imformed by my perants who are flying to Pureto Plata, Dominicana Republic next wednesday 16th that the tour operator has made changes to there flights.

They are due to fly from Manchester at 10:25 on the BY372A flight. but have been told that this flight has changed due to tecnical problems with thomsonfly,s aircraft. Also said that thomsfly have aircraft operating else where so they could be flight changes or big delays. Eg Next day departure.

Anyone know what wrong at Thomsonfly then??
