Group booking at LHR
I need to make a group booking for around 15 or so people (simple return for next year). I've got an hour or two spare at Heathrow on Sunday and was wondering if there's any way of making the booking while I'm there. It would be nice to avoid ages on the phone hearing how busy BA are. I'll be landing at T3 and heading out of T5 3 hours later, with club lounge access if that makes any difference.
Thanks
