Devon and Cornwall police say they're putting extra officers on patrol as a reassurance measure, in response to the terror incident in London.
Seven people have died and 48 are injured, after three men wearing fake bomb vests drove a van into people walking on London Bridge.
They then headed to nearby Borough Market, before jumping out and stabbing people.
The Exeter based airline Flybe is operating its flights to the capital as normal, but is offering anyone who's booked on a plane to London today or tomorrow the chance to change their plans in the light of the terror attack.
The airline says its thoughts are with all those affected by the atrocity.
