Non reliable.
I booked my flights to Florida with them $714.
When XL airways went bankrupt. They were suggesting to either book another flight for $500 or estimate the refund. Out of curiousity I wanted to estimate amount of refund.
The next day they had canceled all my flights without my approval! And did a refund of $124.
When I called them to require that they rebook my flight because they had no right to cancel them, the answer was "we are really sorry we can't, all we can do is give a voucher of $50 on your next purchase with us".
Poor solution. I will never book anything through this kind of agency.
