Jomo Kenyatta International Airport (JKIA) was on Wednesday at a standstill after the Kenya Aviation Workers Union (KAWU) went on strike.
Hundreds of passengers are stranded at the JKIA after flights were disrupted following a strike by aviation workers over a management row.
The workers are opposed to a planned handover of management to Kenya Airways.
The Kenya Airports Authority workers say the plans will render most of them jobless and want the plan to be discarded.
The workers are said to have downed their tools from midnight with fire engines withdrawn from the runway and no planes landing since then.
“Further to the strike by KAWU members, we expect disruptions on flights. Customers on flights after 11am are advised not to come to the airport until further communication is shared. We sincerely apologize for any inconvenience caused,” Kenya Airways said.
Following the strike, JKIA has allegedly been downgraded from its Category 1 status as no flights have been cleared leaving hundreds of passengers stranded.
On Wednesday morning, police engaged in running battles with the striking workers and lobbed teargas canisters to disperse them.
Some passengers were caught in the fracas that left six KQ staff members seriously injured.
The grounded JKIA flights have also affected operations at the Mombasa and Kisumu airports.
