Is the BA Avios Visa airlines rewards card worth it?
I am a proud member of the BA frequent fliers' club (Executive Club). Their service is superb. Their avios (aka miles) are quite useful. However, that is if you're not flying with British Airways, because if you do - you'll pay enormous amounts as "taxes". I've used their avios on Air Berlin, American Airlines and Iberia - several times each, and their prices are very reasonable (including trans-Atlantic flights, although I mostly used it for domestic flights in the US and EU). If you only fly BA - their club charges ridiculous amounts for taxes and you would probably want to be in one of their partners' clubs. Depending on your traveling pattern - I'd suggest American Airlines (if you travel a lot in the US) or Qantas (if you travel to far East). I'm not familiar with other partners' clubs, so can't tell. So whether or not the 50K avios worth the investment is really up to you - it depends greatly on your traveling pattern and where you can use them. If only on BA - not sure if it is worth the trouble (although you do end up with about 50%-70% discount of the regular price when you buy miles tickets).
