I'm probably going to go to South America in late july and returning in mid august and ebookers have quoted me the best price by far, about €1100 each Dublin to Madrid on to Santiago and return via Rio de Janeiro Madrid and on to Dublin. Its not bad all in all but for some reason its up €250 cheaper at other times(around March-April) for the exact same flight, its even about a ton cheaper NEXT WEEKEND to go, even after my dates in August its a bit cheaper. Can anyone explain this, I know July-Aug is peak European summer season but its the opposite in SA.
