I am planning our next trip from Los Angeles to Paris in next March 2020. Right now, there are cheap tickets from British Airways, Finnair, and American Airlines, all less than $300 round trip with one connection.
Connecting thru Heathrow, London, with BA is 1 hour 50 minutes both ways. I understand that there is no TSA pre-screen like they do in Dublin. See my experience: http://www.early-retirement.org/foru...nd-100031.html
Will I be OK both ways, or there are some unexpected challenges in Heathrow?
