Untrustworthy company
When you try to book on their website, you get flashing messages that cheaper airfares are available via phone but cheaper fares are never offered. They put pressure on you to buy travel insurance and other unwanted things. In the past, they were somewhat reliable, but you can't be sure if you will have valid ticket and itinerary after you have paid. If you have an important travel, do not use Fareboom.
