Hopefully this fits under the seat category, F or J on the 787-10 (at least what it appears to be now on LHR-IAH)? Booked a reward ticket into F as no surcharge difference and 27.5k miles difference. Figured worth it to try for that much as haven't done F on BA before, although I could see the Club World seats being just fine and maybe even better on a daytime flight? Opinions and seat recos welcome.
