Hi
We've discussed this at a high level as a Mod team. As the frequent flyer programmes will remain distinct - and indeed the airlines - there is logic in retaining seperate fora to enable discussion. We expect that offers, promotions etc will remain aligned at an FFP level rather than currency (think Amex 241, Gold Upgrade Vouchers). Avios is only a common currency, not a common programme.
It is also worth point out that creating new or merging forums is under the remit of Talkboard. Recommendations to Talkboard can be made by anyone.
