Direct flights to cities in nearby ex-Soviet countries of Armenia, Georgia, Azerbaijan and Kazakhstan were all sold out for Wednesday, the Aviasales website popular in Russia showed.
Turkish Airlines meanwhile said on its website that flights to Istanbul, which has become an important travel hub to and from Russia, were fully booked until Saturday.
The next available AirSerbia flight to Belgrade was posted for September 26.
Google data showed that searches in Russia for “tickets” and “plane” more than doubled after 0600 GMT Wednesday, the start of Putin’s recorded televised address.
