“At some time in the future, we would like to return to a daily service to New York from Liverpool but our experience would suggest that to make it viable we would have to introduce a secondary stop on the route, similar to our Liverpool John Lennon to JFK flights which fly via Knock in Ireland.”
That quote doesn't make much sense, re introducing a stop on the way to JFK when they already have that stop!
Looks as if the GLA/Boston going the same way as LPL/JFK by dropping down from the current daily to four per week split between non-stop and one-stop via Knock.
