Why are airlines permitted to get away with this shit? Booked two bonus flights to SFO this summer using points and a voucher to get free Business Class tickets.
Problem is you cannot use them for returns only one way so I have to book return flights - the price - 3300 Euros each
However, there is currently a campaign which allows me to book 2 economy outgoing with 2 premium economy returns for a total of 2000 Euros (return for both people).
