If your health is important to you, than stay far far away from this tiffs.
They might catch you with a very attractive ticket pricing, but once you'll click the submit button to purchase your ticket then you're in big trouble, and the misery and aggravation will start from that point of time.
Here are the points you can expect.
1. Any little inquiry you'll have and you'll need their customer support's help, your call will take a minimum of 30 minutes of your valuable time (it can take an hour or more some times).
Their customer service are based outside the country in India etc. ("to save them costs"), and you can hardly get a fluent conversation with their agents.
To get an answer on any question related to your ticket, they will ask you to wait 3 to 5 minutes on hold, and they will usually come back between 5 to 10 minutes to continue the call. If you have any doubts on what I just wrote, than I encourage you to call them NOW, and you'll right away see that I was right.
I bought from them a multi city ticket when I was traveling from Montreal Canada to New York and then to Tel Aviv, and I would not exaggerate that it took me HOURS to settle simple changes to my itinerary, when I could of gain this valuable hours by paying only a few more dollars to a local travel agent or through an alternative online travel agent.
2. For your information, if for any reason you'll need to cancel by them a refundable ticket, then you will be penalized by them by a minimum of $450 and up.
When I questioned them on it, that in their terms and obligations of the ticket (when doing the booking) they write a maximum of $250, the told me that they don't have any answer for this and they can only be 'sorry' for the inconvenience (what a shame).
In this case I didn't have any other choice and I was forced to cancel my ticket, and I had to buy a new ticket, because to make a change to that ticket would of cost me close to a thousand dollars.
I warn you. Please don't get influenced by the price only, you'll regret it for life.
