Why is a fanny pack considered a third carry on? This shouldn't be regulated at the gate

2.0 MediocreJennie, Dec 2025
PHL - SEA

Why is a fanny pack considered a third carry on? This shouldn't be regulated at the gate

1. Denial of Basic Needs (SEA): Upon arrival in Seattle, the wheelchair attendant refused my urgent request to use the restroom, insisting on scanning documents first. She eventually took me to a restroom but then abandoned me and my autistic son at an unstaffed, deserted gate for over four hours. When I called the accommodation line for help, I was told to "get someone's attention," which was impossible. My son, traumatized by the prospect of me yelling for help, was forced to wander the terminal to find assistance. 2. Revocation of Accommodations & Threats: At the gate, an agent stated I had no accommodations on file, despite my previous leg having them. When I showed the app (where my bulkhead seat was erased and replaced with Row 14), he denied the evidence. When I attempted to advocate for my immobilized leg, he threatened to "yank me from the flight" if I said one more word. He coerced me into agreeing that I was "asking for accommodations for the first time" before he would allow assistance, effectively forcing me to falsify the situation under duress. I complied only out of fear of being stranded in a strange city. 3. On-Board Negligence and Injury: Because my bulkhead seat was revoked, I was forced into Row 14. With my leg immobilized and unable to bend, it extended into the aisle. During boarding and the flight: 16 different passengers tripped over my injured leg. 6 rolled luggage bags were pulled over my injured leg. The Flight Attendant (FA) was one of the people who tripped and drove luggage over me. I reported the issue to the FA after 10 trips and 3 luggage impacts. He ignored me. He only addressed me later to ask me to move my immobilized leg for beverage service. I informed him again: "16 people have tripped, 6 luggage runovers, I cannot bend it." He provided no medical aid and no incident report. 4. Resolution and Trauma: Eventually, a different employee noticed my distress and my original paper boarding pass showing the correct bulkhead assignment. He asked me to move up. I broke down in tears, terrified that moving would cause the gate agent to remove me from the plane as threatened. We were eventually moved to the bulkhead, but the damage was done. My autistic son was traumatized by watching his mother be trampled and threatened. 5. Post-Flight: I called to report these injuries, but was disconnected after a 45-minute hold. I require a formal record of this injury and these violations.

Larger seats and more room would elevate the experience. Otherwise, it was good!

The rice pudding was terrible. The bread with the hummus was fair. The ravioli was okay. The snacks were great. The two delays were not pleasant. In the beginning I understand, but on arrival we sat for about 30 minutes before getting at the gate.

We appreciated that the flight attendant came through 3 times with drinks or water on the long flight..I was also glad that they were separating out recycling! I would have liked a 12oz sofa can instead of 7oz, but that's a minor quibble. The knee space in economy was also better than most of Alaska's competitors.

No beverages were served on the flight to Vegas as there was turbulence. It was actually one the smoothest flights that I have ever been on. My return flight home I upgraded my seat for $87 and the crew came through the cabin and served every row except mine drinks... I was waiting for them to come back and they never did. I most likely would never fly Alaska again. It was my first time and I've had better service on Frontier... Might as well pay less for my flight and still get to purchase something to drink than pay more and get passed over.

Leg and arm room are horrible. I am not a big person and found it tight.

It was good except there was a loud rattle from the window on aisle 10 DEF,

Had no way to see what gate came in on or what gate connecting flight would take off.

If they loaded the back of the plane first, loading would go faster

Flight delayed missed connecting flight crew not very helpful very frustrating customer service

Our biggest complaint was a major schedule change that was not communicated to us in any way. Luckily the time change went later not earlier so we did not miss the flight. Our email addresses and phone numbers were on file but we received no email no text message no nothing. Short flight so not much to say.

The check in was quick but the counter person didn’t inform me that the flight was delayed. I was also not informed of the boarding gate. When the plane landed there was a mixup at the gate with the ramp crew which delayed the flight further. All in all the experience didn’t meet the standard I’ve come to expect from WestJet

Again, flight was late. It’s expected of this airline now i guess.

Counter representative refused to check my luggage despite paying for it in advance

Delayed 8 hours, This is the 2nd time in a month that my flight was not on time.

Do not fly on WestJet if you have a connection. It failed to integrate with my connecting Delta flight and I almost missed it.

The experience was good just the upcharge of over a hundred dollars was not cool.

Good, a bit cramped in the seat as my neighbour was a bit large

There was a man who was very rude at boarding. On the other hand personal bag measuring box is too small compared to USA airlines,

Air Canada cancelled our flight and reschedule it 26 hours later that completely interrupted my family's long waited Japan trip, it wasn't due to natural reason such as weather but under the company's control. On the day we wasted 9 hours of our time from 6am to 3pm, including a few hours in the customer counter waiting for supervisor to handle our rescheduling. When we came to the counter for rebooking help there were at least 4 employees on the counter but we were told they were not trained to handle customer rebooking, we were also told the supervisor could come 10:30 to handle our rebooking, but she showed up more than one hour later, the end result was exactly the same so the few hours we spent waiting for her was completely wasted; We already prepaid hotel and all the tickets for the our stay in Tokyo so all of the cost for the first day is completed wasted; The $80 meal voucher issues was far less than our financial loss due to the financial cancellation, and it was not surprisingly invalid (as Your company screw up everything possible along the flight), the vouchers were supposed to last 72 hours, when we tried to used it at our lounge next day less than 24 hours from its issuing at a designated restaurant, the worker there couldn't scan the vouchers after multiple tries on all 4 vouchers issued, so we had to pay the food from our own money; For the two return flights they were also full of unfortunate events that caused bad experience and further delay and waste of our time, both flights departed late and the last leg had another significant delay of more than half an hour after touchdown, the gate was for some reason not available so we waited more than half an hour, when we got out of plane it was almost one hour later than the supposed arrival time; The gate you arranged is the farthest in Vancouver airport, also was the luggage pickup location in Seattle airport; We also called customer service for rescheduling help and after a long time wait (more than an hour) we got a call back but the CS representative was equally clueless and unhelpful. Other than a fatal crash, your company couldn't do anything right and provided the worst service possible among the tons of flights we have taken in our lives.

I knew I was going to fall asleep unsettlingly from exhaustion so I warned the guy next to me in advance. The attendant took to checking on me frequently and even insisted I take my snack because I said no while sleep hazed and then absolutely wanted it about 5 minutes later. He was So caring and kind to my situation!!

I’ve wasted 7 hours of my time because of the delayed. ;(

I had boarding pass on my phone. Husband and I were seated together. Agent printed out boarding passes and we were separated for the flight

Could not understand what the attendant was saying during his announcements.

Economy seats always cramped, no meal on international flight, no plugs for electronics, but we got there and cabin crew was excellent.

I paid for comfort plus seats but did not get the extra leg room. When I told the stewardess, she just ignored me.

I did not noticed baggage was separate - I had assumed international flights included luggage, so it surprised me I had to pay to check a bag.

Bad service as well. Another 3hr delayed flight from chicago to Charlotte.

Everything was good. Except Broken looking escape/exit doors over the wings need tending,
