O Connell's Bridge Dublin and Butlers Hot Chocolate.
While I was travelling from London to Dublin you would assume it is a pretty straight forward journey. This year I booked flights with Flybe, after travelling with them in summer I decided to fly with them for Christmas. Upon telling everyone I was asked why fly from Southend - an airport in Essex, near the coast- as I live in South London, closest to Gatwick.
It all worked out for the best as my bag was robbed with my passport in the weeks approaching Christmas, while I ordered a new one I was not sure my passport would arrive in time. I did have my drivers license and could use that to fly between Dublin and London instead of a passport. Ryanair who I usually fly with, require a passport as identification.
Another point to mention about flying with Flybe Fromm southend was the drone delay. With over 100,000 flight delays I could have been one as I flew out the day of the drone interruptions in Gatwick airport. Instead I was in Southend, quite similar to Cork airport and was able to board my flight without delay.
It may be worth looking into trying new airlines and not sticking with your usual routine when flying from London to Ireland as there is nothing worse than a delay especially at a time of year when all you want is to be with your family.
