After lack of help in Philadelpha made us late to board our flight to akansas City, our flight to Kansas City was very good. And the flight attendants were also very good. The only thing that sucked was problems with assistance in Philadelphia caused our bags not to arrive.

After lack of help in Philadelpha made us late to board our flight to akansas City, our flight to Kansas City was very good. And the flight attendants were also very good. The only thing that sucked was problems with assistance in Philadelphia caused our bags not to arrive.

They delayed my flight 6 hours and gave me $12 for food that I couldn't use it anywhere.

I have posted the comments in the first flight leg.

The flight from Chicago to Orlando was delayed inordinately. My whole journey from Lansing to MCO took 9.5 hours is just annoying and frustrating. We can understand the delays may be beyond their control, but overall the journey was so much waiting until reached to MCO. This is NOT the first time for me - but at least 80% of the time in this route. I barely remember reaching places on time.

The delays were not communicated well at all. I was in the airport for over 9 hours with little knowledge of if I was actually going to reach my destination.

The crew in the Vegas airport clearly was having a bad day … they moved on and the crew that checked us in for boarding was great, as was the flight crew. I did get the wheel of my carry on stuck in the overhead bin. Amazing team effort to include the flight attendants, the pilot, and another pilot who was on the flight as a passenger. Finally got it unstuck ✅

Staff are polite,and even offer us to tag our baggages upon seeing us from the entry

Internet is much improved, which is very important to me a s a business traveler. The off boarding of the plane was fantastic. Very quick and very orderly. We had to check our carry-ons before we got on the plane and they were retrieved and available to us very quickly. We left on time and arrived early. All very good things

The Charleston, WV airport was cute. Very good staff and small enough to feel comfortable. The plane had more leg room than bigger planes. Much more comfortable.

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.
