Ryanair has said it will reintroduce 40% of flights from 1 July, subject to government restrictions on air travel in the EU being lifted and 'effective health measures' being in place at airports.
The airline has said flights will run on 90% of its flight network.
Currently the UK government advises against all non-essential travel abroad, but even if this is lifted by 1 July, arrivals into the UK, including holidaymakers, will face 14 days quarantine. That makes most holidays impractical.
Yet Ryanair customers will not be able to get a refund if their flight is running.
However, if the flight is operating standard terms and conditions apply. Ryanair is not legally required to issue refunds even if the UK ban on non-essential travel prevents passengers from travelling to the airport, or because of the FCO warning against travel abroad or quarantine rules.
It's likely to leave many families, who booked summer holidays months ago, with expensive flights they can't take.
It's not clear yet. Ryanair had waived its change fee for customers who had flights leaving up until 31 May. It hasn't said if it will extend this waiver for flights in July and August.
It's a huge risk, even if you are willing to quarantine at the end of your summer holiday. Come July, if Ryanair starts to cancel flights again, you could be left waiting months for a refund.
Hundreds of Ryanair customers from March are still waiting for refunds, despite claims the company has paid back most people from that period. Just weeks ago the company said it could take up to six months for a refund, too.
You likely won't be able to get any form of insurance either, especially to cover you for Covid-19 illnesses, so it would be a risk all round.
