Parties of children from three Shropshire schools on trips to New York are reported to be safe, well and in good spirits following "super-storm" Sandy.
More than 80 pupils from Idsall School in Shifnal, Shrewsbury's Priory School, and Lakelands School in Ellesmere, now face a wait to learn when they can return to the UK.
Idsall School's chair of governors, Mark Blackstock, said: "Pupils have been encouraged to text message their parents to let them know that they are OK and we are speaking with the staff in New York to get as much information for parents as we can.
"We appreciate parents may be worried, but we can assure them that the pupils are safe and in good spirits, with teachers following the appropriate advice from the New York authorities.
"We will keep parents informed of any developments regarding flights back as there will inevitably be some disruption from so many cancellations taking place."
In a statement issued on its website, the Priory School said British Airways had confirmed that the group's scheduled flight home had been cancelled.
The hotel being used by the group from the Priory School is in the centre of New York and is therefore not at risk of flooding.
Lakelands School said staff looking after pupils in New York reported that the experience "on the ground" was far less alarming than TV pictures had suggested.
