Took a cab to the Airport. Security is super-tight there. Non-travellers are not allowed inside the check-in hall. They have to obtain a visitor’s permit and stay in a separate waiting area. The check-in luggage got screened directly after entering.
British Airways was good for a laugh. There’s no extra fee for taking a bike on the plane. However, the bike box counts as over-sized luggage and they charge 25 British Pounds for that.
At the carry-on luggage screening, my backpack was taken apart completely and they wondered about my stove, a box of rechargeable batteries, and my stash of foreign coins. Also, they didn’t let me keep the duct tape I’d bought to possibly fix the bike box in London.
Finally, there was yet another security check by BA personnell before boarding the plane, but that was harmless.
