Find Cheap Flights from London Heathrow to Dublin (LHR - DUB)

I have flown LHR - DUB a couple of times in the last month with BA and a couple more times in the last year from LHR-DUB and not once has the flight left LHR on time and landed in DUB on time. I find this very frustrating, they appear to always be delayed by 1hr + which make it very challenging to make onward travel plans and has resulted in overnight stays at my own expense.

It was short

I was exhausted and so was my flight buddy. The staff was helpful and quietc and got us on board and to our destination without us having to think which was great.

There was no entertainment for that flight.

The service was terrible and staff was unpleasant

Quick flight.

Flight was delayed, plane didn't take off for a long time after boarding.

They tried to help me in person by making a phone call to the security gate.

Despite the call to security (I guess it was to the security gate? Not sure) it seemed standard the way they spoke, not as if anyone seemed empathetic to my situation as I am a graduate student and was in dire need of returning to Dublin, Ireland for work the following morning. I have had a different experience with different British Airways representatives. The customer service on the phone seemed good, but in person, it just felt like robots following policy unfortunately. I spent $150 for a roundtrip flight and could not use my "Return" portion of my ticket. I arrived to the security gate and I could not be let in. My flight was even delayed which should have allowed me time to scan through security but it did not. My phone is temporarily unavailable as it is in the shop for repair, while I navigate a foreign country without the use of maps or access to email so easily. I checked my email at a random hotel in London for 1.5 hours, and 30 mins after I left, apparently an email was sent by BA to me, alerting me that I could check-in my luggage, instead of having to take it on-board as carry-on. All these details would have been nice to know a little more ahead of time. I wish I could be refunded for my flight, as that was the last flight of the evening, and I ended up having to go to Air Lingus to pay nearly 300 pounds to get on their last flight back to Dublin. As a graduate student, working on my thesis and fulfilling a job here in Ireland as the final leg of my Master's degree, any money saved is a help. Forfeiting half my ticket, and purchasing a new one twice the price of my original was not something I was expecting. I was an emotional wreck getting on-board my other airline's flight. Just not a positive experience that resonated with me overall :( I wish I had more positive insight to share, especially on social media or Yelp about my experience to London and back with BA. Plane was small, and complimentary drinks were not served as every flight I have ever been on in 30 years, and that is several several dozen, have ALWAYS given at least a drink, even if they didn't have peanuts/pretzels. Pretty disappointing..

The staff onboard the flight was friendly.

There was a last minute gate change that was not announced until boarding was closing, so I had to race across to the other side of the airport to catch the plane. There was no food/drinks provided on the flight.
