Redemptions for 2019 are now starting to go on sale (since BA release reward availability 355 days ahead), but BA are yet to release the calendar for the year, showing which days have peak pricing and which are off-peak.
This means that we only know on the day whether it's peak or off-peak. So, for example, today availability for 7th January 2019 went on sale. We now know that it's a peak day, but we don't yet know whether 8th January is. This makes showing pricing very challenging 🙈
As a result, I've updated the site to show available days where we don't know the price in grey.
If you hover over a date for which we don't know the price, you'll see a "Price unknown" tooltip.
BA haven't tended to release the full picture until half way through the year (the full calendar for 2018 wasn't released until June 2017).
Hopefully the data will become available before June - and in the meantime, we'll be looking for alternative ways to show pricing.
