I would definitely use a Linus again, the price was right, the service is excellent. No delays. Wish I had a direct flight from my hometown Detroit.

I would definitely use a Linus again, the price was right, the service is excellent. No delays. Wish I had a direct flight from my hometown Detroit.

At check-in the unmanned machines said QR code was invalid so had to queue for over an hour to check in bags

i used to fly aer Lingus regularly but due to price - poor seating etc i have been using other carriers - i now have aer lingus in my state and the price is always the highest - i have flown to Ireland 11 times in last 24 months and have not used Hartford because of price

Nicest staff I’ve experienced on a plane! Good food, great entertainment, and they gave out little blankets that my kids loved. All in all, great experience.

Unfortunately the flight was delayed for 50 min. Just as we were about to board so that was a drag. The boarding was average. The bag check in process was new to us and efficient. And the flight itself was smooth- basically no turbulence.

I liked how they looked after couples by providing a row of 4 seats if available.

Food was very bad. Boarding was disorganized and messy. Crew was friendly

It was ok not that much because I always travel with Emirates airlines, Etihad, airlines, Qatar airlines compare to them food and comfortable was too low . Staff was good . Helpful

I believe it was short flight in plane I understand not that much compared to other airlines but weighting for checkin was too long need extra person for checkin or Atleast someone to let the customer knows don’t worry someone will be here shortly.

Noted in last review. Good to know, though air Lingus on European flights does not offer any food or drink, even though we were on the plane for 3 1/2 hours from Naples to Dublin everything you had to purchase even water.

I’ve never had worse food in business class ever!

Checked bG chstgr was extremely high. Over $120. It was s bsit and switch knowing an international passenger would have t9 check a bag.

First, communication was terrible. The gate on our ticket was not what was reflected on the airport screens and TAP personnel were not present at either gate to answer questions. The flight was delayed and there was no announcement. Also, there was an equipment swap to a smaller airframe which affected our level of comfort. The root of all these issues was as a lack of communication. With air travel in foreign countries already being a stressful affair, lack of communication needlessly raises the level of difficulty.

Checkin was very slow, we had checked in online and hoping we could do a bag drop at the airport. However everyone with checked bags had to queue up and it took over 40mins. Our advice arrive extra early or you will be rushing to the gate.

On time, politeness, food okay but entertneiment mediocre with only old movie and the so called new we’re 2 or 3…

Do you have a bad service And And treat customers terrible

Awful. I told them to cancel my return flight and they didn’t then charged me +$800 days before the flight for a biz class upgrade bid. When I called to confirm cancellation and get refund on buz class upgrade they said I had to go thru orbitz and it was too late. Scammers. Beware.

Little leg room in business. I am tall and could use more.

Was a cheap flight and it got me to Portugal on time. For economy there was ample leg room and the flight attendants were pleasant and helpful.

Flight was packed. This was a very uncomfortable experience. Boarding process could be explained better. Despite recommending a window seat when travelling with a pet in the cabin, the seat in front of me had less space than the center and aisle seats. For Premium Economy, the seats were crammed with minimal legroom. I hate to think what Regular Economy was like. The cabin crew missed me at first when handing out meals. When my meal eventually came, there were no utensils. I'd originally booked to fly Business Class; those seats didn't look that great either.

Flight was over an hour late. Boarding was really messy with long queues at the plane.

Cabin crew couldn’t be less interested. Cabin manager was the most arrogant and the rudest I’ve encountered in many years.

Good but both flights were delayed by nearly one hour making boarding tedious. We had to wait with no information

The worst flight ever. Sitting in plane for 4 hours delay and then they change crew. No water or food offered to any passengers including children in that time. Only 2 toilets out of 3 operating for flight with 200 passengers. Only enough food available for about 7 rows of seats depending where you sat you might be lucky. Cabin crew very unfriendly.

This was the worst boarding ever. We were kept in the boarding bus for almost 40 minutes without any information or update. Very uncomfortable beings squished with another 50 people and not knowing what was happening.

Delayed and changed Multiple times after booking necessitating many. Travel changes ; a bit of an issue

The flight arrived within 15 minutes of schedule. We hate the cattle-like boarding process seen often in Europe. After your boarding pass is checked by the airline staff, you wait standing up in an area with no seating for several minutes.

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

The punctuality of f the flight was super: we left on time and arrived about 20 minutes early - and the cabin crew were both friendly and efficient. The only downside was that Ryanair appears to have resumes its old obsession with sizing cabin bags again after a long and welcome absence.

Flight details on public information screen were misleading and wrong.
