I just priced a trip to Boston for July from Cork (Norwegian) and Shannon (EI). 2 adults , 2 kids with checked baggage, seat selection and standard food. Dates are 20th July, returning 26th.
From Cork allowing 2hours at airport, flight time 7h 45 min, and 1hr 6min transfer (google maps) to the city. Total 10hrs 51mins , cost €2,997.
From Shannon allowing 2hr road trip, 2hrs at airport and 6hr 50min flight time is 10hrs 50 mins , cost 2,422.
On these dates it is €575 Euro cheaper from Shannon with EI.
Has anybody else made similar comparisons?
