British Airways is axing its routes to St Petersburg and Kiev this winter.
The UK flag carrier says its services from London Heathrow to both cities will cease on 3 October. It says both routes are "no longer commercially viable".
The IAG owned airline says it will offer customers the option to rebook flights with other carriers.
