There are a number of considerations for travellers too. Some of which depend quite heavily on how the situation develops in coming weeks.

The MYBA charter agreement force majeure definition does not include any health-related reasons, though note that as soon as health-related reasons gives rise to a 'governmental act or regulation', such reasons may well fall within the force majeure definition.

Cancellation - You're Ill

Unless and until a crew/vessel become quarantined or passengers are told by the government not to travel to certain areas, Coronavirus is not likely to constitute a force majeure under the MYBA Terms.

Should you fall ill and be unable to travel, or have to self-isolate, you will need to look to your own personal insurance (or a policy of charter insurance) to see whether or not it covers your cancellation.

At present, it is likely to be only the owner's goodwill that sees charterers getting refunded.

Cancellation - The Vessel/Aircraft is unavailable

It may be that the vessel or aircraft is unavailable (perhaps because the crew have been quarantined) - the MYBA charter agreement force majeure definition does not include any health-related reasons, though note that as soon as a health-related reason gives rise to a 'governmental act or regulation', it may well fall within the force majeure definition.
