The carrier said it has reduced its flying programme in the region due to "continuing uncertainty" and instability affecting airspace.
As part of the changes, British Airways has cancelled all flights to and from Amman, Bahrain, Doha, Dubai and Tel Aviv until later this month, while services between Heathrow and Abu Dhabi will remain suspended until later this year.
The airline said it was keeping the situation under constant review and contacting affected customers with alternative options.
