Rafic Hariri International Airport, Beirut (RHIAB) is not too far from the city and it operates its own fleet of taxis, which though convenient, are a bit on the expensive side. As an alternative, taxis can be pre-booked from taxi companies:
Allô Taxi (tel: (01) 366 661; www.allotaxi.com.lb)
Charlie Taxi (tel: (01) 285 710; www.charlietaxi.com).
Another option is to take a cab from one of those available outside the airport. Usually they charge according to their whim so it is better, if before hiring, you decide on the fare to be paid.
