Hi,
I am trying to purchase 2 tickets for friends from PRG to BOS in Aug or Sep. Right now the lowest fare is on AF for about $658. Does anyone know of consolidators or best sites for booking trips originating outside the USA? It is also difficult to book and hold such a ticket online. These are youths so I will also check with that STA travel agency. At one point AF had seats for about $500 but the T and V is now sold out. It is weird that ITA Software shows the T and V available, but Expert Flyer and AF say it is unavail.

This is where one really needs access to CRS.

Thanks for any tips.
