I know this is of very niche interest, but Ukraine International has gained slots at London Heathrow.
It will launch three weekly flights to Kiev from 17th December.
Departures will be on Thursdays, Saturdays and Sundays.
The airline will use a small Embraer 190, although some services around Christmas will use a Boeing 737. The existing service to London Gatwick will continue.
Ukraine is not in any major alliance so there is no easy opportunity to redeem or earn miles from these flights.
