Nice one (good for business class too). The flights I'm looking at would get 100€ in total cheaper than my alternative, however the conditions of this promotion (and the way it actually works) only allow for the outbound flight to begin in Greece (which would mean I'd have to book my actual outbound at a later point in time, which could lead to its price increasing beyond the 100€ I'd have saved by booking the inbound now... Why can't the hunt for cheap tickets be simpler? ​​​​​​).
