Recently received an offer to switch CDG-SIN to a different date for 150€. Obviously this felt low and I didn't consider it, but it feels even lower knowing that the offer for European flights is 50€!
What was interesting is that I had a connection to SQ on the same ticket, but neither the email nor the Swing website showed anything beyond SIN, so I'm not sure what would've happened to my connection had I elected to fly to SIN a day or two later...
