1:35 pm GMT Update: Heathrow-to-JFK flight leaving in 25 or 30 minutes. Arriving 4:45 pm EST or thereabouts. Earlier: Several weeks ago I booked a return from London’s Heathrow because there was something interesting to do in the London area. Then that thing didn’t pan out. Changing the flight to Paris was way too costly, or certainly less expensive than taking a Eurostar from Gare du Nord to London/St. Pancras at 8:45 am this morning, which will happen an hour from now. Then a 2 pm flight back to New York. No wifi on the train or the plane so there won’t be much filing except for what I can tap out on the phone.
