Somtimes I like to try to get a little bit more comfortable on my tours. For the trip to Paris, I tried to get upgrades to business class with Optiontown.
They offer the possibility to upgrade your flight (for some airlines – SAS is one of them) for a fee that mostly will be much cheaper than to buy the expensive tickets. You get confirmation (or not) 3 days to a few hours before your flight. If you can’t get an upgrade you get your money back, minus a fee of 1 Euro.
I had to pay 68 € to upgrade one way (2 flights). Fast Track, extra luggage, a meal and drinks on the plane, lounge admission. For me, it is worth it. 🙂
