Brexit: Will flights be disrupted?

The EU has agreed measures to allow 'basic connectivity' for a year, to prevent planes being grounded the day after a no-deal Brexit. UK Aviation Minister Baroness Sugg has confirmed that this will be reciprocated. This doesn't provide the exact same access as before, though. It allows for 'point-to-point' trips - from the UK to another EU country and vice versa. But it doesn't cover onward flights to other European countries - or flights by EU carriers between two UK cities.
