I never got to Cabo. It took 2 hours for Delta to de-ice the plane in Milwaukee. Because of the long delay we missed the flight to Cabo. We asked Delta to book us on another flight to get us to Cabo today, Delta reps said nothing was available. Delta gave us a discounted coupon for a hotel in Atlanta and rebooked us on a flight to Cabo tomorrow.

Just be honest and keep us informed. Bonus: United sent me an email saying that connection had already left (it hadn't - thanks United! - awesome service as always!)

Crew was courteous and polite! Entertainment system had some great movies at no additional cost.

Poor communication between delta, KLM and Air France meant that I couldn’t check in online and get a digital boarding pass. Furthermore I couldn’t use the check-in kiosks because my name was listed as Reidmr instead of Reid, which meant that my boarding pass did not match my passport. Overall this caused unnecessary delays that were compounded by the fact that I couldn’t use my TSA precheck. My main problem on the plane was that I had to struggle to get water served to me. It’s always so dry on planes and I would have liked to be able to get more than one tiny glass of water at a time. Also, would have loved a window at my window seat. Plus no WIFI!?

una valija se perdió. Eso desató el descontrol que tiene KLM para seguir el equipaje. No hay como hacer tracking. No hay un teléfono a donde hablar, la web está desactualizada y con información equivocada. Direccionan a usar canales de twitter y facebook que no responden. Primer experiencia en KLM y no pienso nunca más usar esta aerolínea. Llevar el equipaje o resolver un problema sobre valijas es de lo más básico de una aerolínea y no lo hacen.

We were stuck on an aisle where the seats don't adjust on one of the flights, but it was a relatively short flight. The boarding process was a little disorganized, but we were able to get on the plane quickly. The worst part was the home airport. I don't know how much control Turkish airlines has over that airport, but the bathrooms we're absolutely disgusting.

The Lufthansa crew is always wonderful as always.

screaming and kicking child behind my seat, with no way to "escape". I had a severe cold and that was certainly not something I needed, I tried to get some rest, but that was impossible. The seats are getting smaller and smaller, hardly any legroom whatsoever. Also, what I had planned on bringing on the aircraft as carry on (which was my work equipment, tablet/printer etc), I had to check in as luggage because it was "overweight" meaning more than 8 kg and pay ADDITIONAL $200 (in addition to the $100 I already paid for one suitcase). I've seen many passengers with "heavy" carry on, which they were apparently allowed to bring into the cabin without any problems. I had never had to pay for any carry on, and I am seriously considering using another airline for future business travel.
