QR1 arrives T4 1800.
BA1426 departs T5 1920.

J throughout. I'll be at the front of QR1 so off first, UK passport, HBO, I know T5 like the back of my hand and have many years experience of belting through it to get the last flight home, notwithstanding all of which this QR1-BA1426 combo makes me nervous. If it fails, it's not a disaster: just another night at the Sofitel or Premier Inn, instead of in my own bed.

I'd be grateful for thoughts/input, please.
