Ground staff at Manchester very helpful

Information on KLM website and flight status said 50 minutes delay and was never updated with the true status. 3 hours before we took off. KLM blamed the fog at Manchester but to be honest most other flights seemed unaffected. Put up in an IBIS hotel and fed substandard food and shitty hotel room with an Aircon unit that clunks into action every 30 seconds keeping me awake. It's external so I can't switch it off. Being given a 10 Euro voucher for food at the airport when most food and a drink will cost you 12 to 15 euros.

The outbound crew was terrific. The flight itself was fine. We even arrived early.

Upon deplaning in Cancun, ALL passengers are put on a bus and driven far away from the terminals to an arrivals area. Those of us with connecting flights are royally f*cked at that point, especially if your connection is short, as mine was. The so-called shuttle to the departure terminals, which are entire kilometers away, was to arrive in like half an hour. HALF AN HOUR. Who has this time to spare?? The alternative to the shuttle is paying a taxi that charges a hefty fare--and God help you if you don't have cash. The departures terminal was swamped and only thru begging assistance and line cuts did I make my connection...and then only by the skin of my teeth. It was a complete nightmare.

First class accommodation was great! We had about a 3-hour flight and would have appreciated a blanket, pillow and a headset.

I didn't like that first class was checked in first at the counter. But everyone rode on the same bus and disembarked at the same time so first class didn't really board the plane first. Some of the TAP counter employees were very unhelpful & actually dismissive. We had gate 19 and there was no sign of activity when it was time to board. When asked some counter employees, they couldn't care less. You should post something at the gate assigned about a gate change or delay. A lot of passengers were confused and uninformed.

I love flying TAP because I love having extended layovers in Lisbon. Lisbon itself, including the airport, is easy to navigate. The food is great and the culture and architecture is gorgeous. For shorter trips TAP doesn't have as many amenities as other airlines, but on this trip the typical video screens with movies, music, etc. was available.

In this particular flight there was a male airline attendant who was fabulous and who could speak many languages, including German. I noticed the other airline attendants seemed to be giving him a really hard time and weren't friendly at all. In fact, I rang a bell to ask for attendant help at one point and no one came to help. I was just a seat back from the area where the helpful airline attendant was available. I think that overall TAP flight staff could be a bit more open to being friendly. However, on the ground in Lisbon I've found the staff to be amazingly helpful.

Food was ok

The customer service I received was horrible horrible horrible especially from the check in counter the were very rude . After booking my flight on kayak I called TAP customer service just to make sure that everything was fine .I asked them about luggage they said I had 2 free and a carry on when I got to the airport said I had to pay for the 2 i said no told them that i called TAP they didn't wanna hear it i asked for the manager she I am the manager and you bought a discounted ticket and there's no luggage with this ticket only acarry on in a mean way if you want the you have to pay $90 for each I tried to call TAP can't get through them when they finally got through them the guy confirmed that I ve called it on the records but it said now it's too late to do anything I am already at the airport that I have to pay and contact them later. I wasted good hour and a half on this and I had to pay $180. After all that at the boarding gate they announced that they will call by zone .they called especial need called frequent flyers zone A never called zone B all they said last minute was this is the final call for flight #.... and I was right in front of them and guess who were the people making the announcement yep the same people at the check in counter

My flights were so behind I missed my connection for Toronto to Tel Aviv and was rerouted to London and then Frankfurt but the plane was late getting there as well. Air canada had no crew on the ground and over and hour wait for customer service on the phone so i had no way to find out what my reticketing status was. I was passed off to numerous other airlines and sent through the airport to the incorrect terminals in heathrow causing another missed flight. Air canada did not accept the responsibility to maintain my reservation and get me to my destination efficiently. Even when I spoke with a phone representative the person was rude and never sent confirmation of my flights so I had no reference point for flight numbers or air lines. All of his added up to more than 13 hours of delays on what was already a 24 hour trip. Worst travel experience of my life.

The overhead bin did not stay down low enough so that I could place my bag in. It would lower then before I could place my bag raise slightly by a few inches. For someone of my height (5’5”) that was problematic. Fortunately another passenger saw my dilemma and held the bin lower to its full opening capacity. This also momentarily slowed down the boarding process.
