TAM join Oneworld on the 31st March and despite it still being the 30th here are already available for redemption using Avios. From the searches done so far availability looks not too bad and the taxes/charges are very reasonable. Plus there doesn't seem to be any time restrictions on their domestic flights like there used to be when using DC miles.

I've flown TAM both short haul and long haul several times and always enjoyed flying with them although their long haul J seat is now looking a bit outdated.

Edited to add.....after more searching availability isn't as good as I thought.
