In secondary schools, pupils eligible for free school meals are still, on average, missing one day of school per week.

Then there are the various methods of communication to keep across."There's too many ways that the school can communicate with you," said Ruth.

"We have a regular newsletter, then we have another sort of weekly newsletter, then we have another email update... then there's an app they launched this year, which I can never get into, one that's really stressful and then never remembers your password... then we also have Teams, then there's ParentPay... so it's just this myriad of communication."That's all before the parent WhatsApp groups."To be honest, that's a lifeline for me," said Ruth of the WhatsApp groups.

"There are some parents who are maybe on the PTA or more involved and they seem to know what's happening and they share it... it's almost like we've become reliant on them to tell us what's going on."So how does she keep track of it all?

"Quite badly," she laughed.

"It's kind of in my head and I will put things in my phone calendar and just keep track through the WhatsApp group where somebody will say, 'oh, remember, it's wear red day tomorrow', or 'remember they've got to take a packed lunch'."The west London airport also reported it had the "highest departure punctuality out of the major European hubs" with 99% of bags on the planned flights and 97% of passengers clearing security in under five minutes.

Chief executive Thomas Woldbye said: "Last month showed Heathrow at its very best - we successfully navigated our busiest April ever whilst our service levels took a further leap forward."Mr Woldbye said work was already ''under way across the airport'' ahead of the busy summer ahead.

"We're providing great value for our passengers and I'm proud of what we've achieved in collaboration with our Team Heathrow partners so far this year,'' he added.Some airlines which use Heathrow have branded the airport the most expensive in the world for passenger charges.
