Star Alliance operator EgyptAir is preparing to offer additional capacity on the route from Cairo to London, following the temporary suspension of British Airways services.
The Egyptian ministry of civil aviation says it has "increased" the seat capacity of EgyptAir flights on the London Heathrow sector in response.
British Airways is halting flights to Cairo for a week owing to security concerns, although it has not specified their nature.
EgyptAir says that "additional flights" have been assigned to accommodate passengers affected by cancellations from other airlines.
Extra services will be provided through deployment of a Boeing 787 on the Heathrow route, says the civil aviation ministry.
Lufthansa had reportedly intended to suspend Cairo flights as well, but appears to have backtracked on the decision.
