I know this sounds like an odd thing to do but I am travelling for work soon.

Our policy doesn’t allow collection of miles/points but I want to select seats and ideally access the lounge using my silver membership.

Is there any way to do this? Can I remove my BAC number after accessing the lounge?

That seems quite a mean thing to do! Not even sure how a company could stop you claiming the points afterwards anyway…

Yes, the livechat service is able to remove a FFP number from a booking:

It’s a public sector organisation and it’s stated in our terms and conditions sadly. It’s a disciplinary offence to claim the miles and use them for personal use.

Thank you

It is very very straightforward. Once through security and past the lounge dragons you call or chat and have it removed. Once done you can add via MMB for the return leg and follow same process.

info this but then add my AY plus number.

You can track the miles and use them to book a flight or buy on board on the works flight. You will need the BAEC number for lounge access which will save the organisation money on expenses for no subsistence. If it's short haul the avios in Y is that minimal you'll barely have enough for a cup of tea on board

And how can they police/check that? Is it not private personal data between your and the airline?

I thought you could gift Avios to charity?! Surely that would be reasonable - after all the company has paid for them in the ticket price.

Surely you can access the lounge without having your ff number on the booking? Show your card/ecard on entering.

Seat - pay, take what is offered or call the relevant "silver/gold/ etc line".

Airlines don't do FF schemes out of the goodness of their hearts. They are there to skew spend in their direction.
So I can appreciate that some organisations may ban collecting miles.
Using a personal FF scheme to select seats is also against the spirit of why the miles ban is there for work travel..
So I would be tempted to not even try

ps. a daft policy, but I don't entirely disagree with it. I used to have similar restrictions - donate the points and submit your statement/screenshot to show that they were gifted. If edited, a friend suggests that one should keep an eye on your balance/total if visible, with subsequent submissions in mind.

Whilst I can see the argument for this, if I were a public servant, I'd be making damn sure I never travelled outside of my contracted work hours. Quid pro quo and all that.

Not always. A corporate travel contract may no include ff miles/avios/points and/or earning status and/or benefits from status. A lounge entry has a theoretical cost. But good airline ~ travel agent reservation software should lock out that anyway. With corporate travel contracts the price paid can be well below retail.

Sometimes companies / firms don't understand how these things work.
I had a colleague who was forced to fly Virgin rather than BA. He had status with BA but not with Virgin, but Virgin was slightly cheaper (but not at all materially given the total project travel budget!!). So Virgin it was.
In the end, Virgin had an aircraft swap, so he was bounced from the flight - resulting in a day's delay and loss of client time, etc. Had the same happened with BA, he'd have been protected due to his status.

sometimes you just have to bite your lip and accept you can't turn the corporate tanker around. One of the big banks I used to work for had wangled some government funding for a particular project in my area. It needed staff to travel between locations, but because it was being publicly audited, there were different (lower) standards required for travel- think Ryanair rather than BA, and Britannia hotels rather than Hilton.

We can debate whether you'd want to inflict a stay at a Britannia on your worst enemy, but that's how it was, and there was no policy mechanism for the bank to just cover the difference to let the staff stay in a better hotel.

Of course, Britannia was also not a hotel chain that was in policy for staying at, full stop. Nor was Ryanair an acceptable airline. So. Stalemate.

All I could do was escalate all the way up to a board level person to approve these egregious exceptions to policy (I.e. spending less money and getting the job done) At least the question of earning airline miles was moot on Ryanair...
