I booked a business class ticket with them, and that was a massive mistake. The airlines ended up cancelling one segment of my trip, so I needed to rebook. Unfortunately they're just not a travel agent. They're simply a ticketing middle man. They have nothing to offer if your flight in case of cancellation or change. Phone lines are only for catching new reservations, and will not pick up if you choose option #2 (existing reservation). Email correspondence is super rude and will completely ignore your request. They really have no time or will for customer service. Use them at your own peril.
