I booked with fareboom NYC-ZRH-NYC on Swiss in August for $618. Everyone wanted much more. Found it through skyscanner.de incognito.
8 tickets. All come up on Swiss website.
I don't foresee any problems.
For 8 tickets, I would have tried a good TA..You booked Basic Economy?
That fare sounds like basic economy (K class). No changes or refunds. Fly or lose.
$60 for first checked bag per pax per direction.
Regular TA would likely be higher (just so he can earn a living). Fareboom made between $5-$10 per ticket. They are happy with that since its all done automatically through the website.
