Online plane tickets in Lebanon

Yes

You can use Kayak to find the cheapest tickets, and it will also give you a link which you can follow to buy the ticket, usually on the website of the airline.

I've heard that some airplane ticket websites monitor your cache and increase the price ticket if you keep searching for the same flights ... Can't say this is certain but it doesn't hurt to clear you cache if you are searching for one

Make sure to check out Hipmunk and Momondo as well.

If you're traveling somewhere near, check out Pegasus, I've had many instances where they were cheaper by a long shot.

Indeed, they're the only budget airline to fly out from Lebanon to Europe. Do note that they don't have any direct flights, they all go through Istanbul's Sabiha Gokcen airport.

I have always used e-dreams. I don't know how it compares to other websites, but it's a good price comparator.

I user Expedia.com for me and my family,
Once i bought a ticket from an airline i forgot its name through expedia, and then i checked the airline's website and noticed that the ticket was cheaper, so i contacted expedia and notified them about price issue, they went and checked then confirmed; after that they refunded me the difference and gave me a 50$ voucher (though i never used it)
