"Ok, so far but depends on whether we are met on time etc.
The plane gets into Heathrow, if on time at 7.15 a.m. If it is delayed we may be delayed getting through customs etc. Have not been through Heathrow for six years.
I shall ring the number you've given. It may be more like 9 a.m. before we can get to the taxi. Just don't know. I do not expect ridiculous taxi penalties, given the issues with airports. Thank you---Roland Perry"
