Took me over 12 days to resolve, just a few tips;-
-Try to find an equivalent ticket on a different date (route/class/ 4 month/12-4 month/ period) when searching by price (I found just 1 week in the whole year).Go through the flight selection process and note the final price.
-Then search by schedule on the same date(s) check the price, initially when I tried, the 'schedule' fare was nearly $100 more than the 'price' fare, this was eventually made the same, but still more expensive than prior to the website upgrade..
