I am BD Gold and UA1K (*G).

I am looking at buying a tiny fare for travel tomorrow. (Tiny? It's a hundred and sixty quid...)

On the bmi website, the fare basis is HBABY. So this is a baby tiny fare.

I'll want to credit to UA - I get the regular credit for that, I guess (250 each way). I think I get lounge access. Anything else I need to be wary of? Do get? Don't get?

The same flights are available on Travelocity for within a pound of the bmi tiny/baby fare. Any benefit to booking it that way (bearing in mind I'll credit to UA)?

Or, for £4 extra a segment, I could buy standard economy, but I think this would only help if I were crediting to BD?

I have upgrade vouchers left - they're still usable on LHR/GLA, yes?
