It may be two years since lockdown was first launched and almost all restrictions will be dropped in England from April 1, but Covid-19 is still around.
Countries around the world - and within the UK - have their own rules as the pandemic continues. Often these differ from England, where wearing a mask is no-longer compulsory.
All this means that the rules for wearing masks on planes can depend on where the airline is based, as well as where each plane is travelling to and from.

Jet2 became the first airline to drop mask requirements. But passengers flying on any plane - including Jet2's - to Italy still have to wear masks, due to the laws set by Rome. Passengers flying to the USA are required to wear masks, too, as are those heading to or from Scotland, where face coverings are still required.
Those heading to France, Italy, Austria and Germany are required to wear specific types of mask too, often surgical-style masks with no valve. Reusable cloth masks are not accepted. Italy's law is due to change on March 31, after which masks may no longer be a requirement
Exemptions to children apply, but ages can differ between airlines and destinations. There are also medical exemptions. Those who can not wear a mask usually require a doctor's note and a negative Covid-19 test. Check with your airline before travel.
You are not required to wear a mask in Newcastle Airport, although you may be asked to put one on when you reach your departure gate.
Mask rules for airlines flying from Newcastle International Airport
Each airline has its own rules on wearing masks as the coronavirus pandemic continues. While some airlines do not always require masks, including Jet2 and British Airways, you may need to wear one depending on where the flight is travelling to.
You are not required to wear a mask on a Jet2 flight from Newcastle to Spain, but you are if you made the same trip by Ryanair. But if flying to France, Italy or Austria with Jet2, you still need to wear a mask.

You do not need a mask when travelling to or from England or Northern Ireland, Jet 2 says. But if you're flying to or from Wales or Scotland with TUI, you do, if you are over 12.
If you are flying to Italy from anywhere in the UK, you will need a mask if you are over 12, although that law is set to be reviewed on March 31.
