ID Requirements
 

I've searched BA.com but can't find the answer.

I assume that I can fly domestically using my UK drivers licence as ID?

From Flybe website

What forms of ID do I need to check in at a conventional desk?
A Suitable forms of ID include:

Domestic travel
Credit card, Executive Club card, driving licence, company works card / ID.

Travel to the US
A Passport is required for all international travel.


Seems a bit strange, Executive Club Card as ID???????

However;

What to bring with you:

For international travel a passport and visa, where necessary, is required.
For travel wholly within the European Union a national identity card is also acceptable, where allowed.
When travelling wholly within the UK, there is no requirement from British Airways to carry any photographic identification.
When travelling it is strongly recommended that you carry a copy of your e-ticket receipt throughout your journey. Some destinations may require you to show it as proof of travel at Customs and Immigration.
If you have booked directly with British Airways, either through ba.com or a British Airways Telephone Sales office, and you paid with your debit/ credit card you must present that debit/ credit card at check-in. This is to assist the check-in process and to provide debit/ credit card verification.
When using a Self-Service Check-in kiosk, simply insert your credit card (for identification purposes only) to begin the check-in process.

Indeed. You need ID to check in baggage, but not to fly. And yes, "ID" in this case includes your BAEC card.

Thanks - I used the search function on BA.com that's what I did wrong!

Flown many times domesically. At T5 not once have I been asked for ID when on a domestic, at both ABZ and EDI I've been asked, any my BAEC card was good enough.

If you print your own boarding pass and don't check in luggage you won't be asked for anything.

If checking in luggage then your BAEC card will do nicely, thank you.

Good luck tomorrow. Sit on the port side and you'll see where you'll be working as the plane makes its approach!

A view of the 'office' from the plane bonus.

Thanks for the advice all.

Until the scanners at the gate crash!
i always have my passport/driving licence just in case.

Exactly... or the security person doesn't push the 'take photo' button properly at security. This has happened to me. Definitely take photo ID just in case.
