PRESIDENT BIDEN PLANS TO ANNOUNCE ON TUESDAY THE UNITED STATES WILL BAN RUSSIAN FLIGHTS FROM U.S. AIRSPACE FOLLOWING EU AND CANADA - RTRS

This echoes a report from the WSJ which earlier noted that an order barring Russian-owned and -operated aircraft from U.S. airspace is expected to be issued as soon as within the next 24 hours.

The U.S. move would follow earlier prohibitions by European and Canadian authorities. The restrictions, which Russia has retaliated against by issuing a similar ban on European flights, have disrupted airline flight plans as Russia's invasion of Ukraine escalates.

Meanwhile, in a potentially far more ominous development, Politico reporter Lee Hudson tweeted that Boeing has suspended aircraft maintenance and support services for Russian airlines,

"We have suspended major operations in Moscow and temporarily closed our office in Kyiv," Hudson tweets, citing company statement.
