I thought others might want to know about this statement today from LNER if they are considering a train journey. Unfortunately, it doesn’t offer you much reassurance if you are feeling vulnerable to Covid infection (note the last sentence):
“As UK government guidance for England on social distancing is changing, you may be seated next to another passenger when travelling after 19 July. If you booked a ticket before 13 July, for travel with LNER from 19 July onwards, we’re keeping your seat socially distanced. However, customers with flexible tickets may take seats around yours if there is limited space onboard.”
