Easily the most comfortable I've ever been in TATL economy. Lufthansa's 747-8 is set up strangely: the main deck is arranged First - Business - Economy - Prem. Economy - Economy. This means that if you can book a seat in the forward economy mini-cabin, you get dedicated cabin crew, no other passengers walking through your space to get to the bathroom, plenty of bin space, and – best of all – a lot of aisle space to stretch your legs. Row 16 aisle seats are especially good, as the bulkhead between J and Y doesn't extend all the way, and therefore you can stretch your feet out. Food was actually excellent (for economy), hot and flavorful and generous, with snacks available mid-flight. Beverages also tops – gotta love Lufthansa for offering Campari (!) and more than one wine choice.

Entertainment (music and movies at least) was up-to-date but not very interested. Boarding and transit security in Frankfurt was anxiety-inducing – between getting to the US departures area and additional screening, it took more than an hour from deplaning to getting in line. Boarding w/o group numbers was an exercise in patience. And the terminal wifi is so spotty!

Serve was normal and so was the food.

Left the terminal building by bus to the aircraft. Had to exit the bus, WALK ACROSS the tarmac and up a set of stairs to the plane. REALLY, British Air couldn't find a proper gate at the terminal? What if it had been raining or my elderly mother that needs a wheel chair? BA needs to solve these problems fast if they want my service in the future.

The boarding was chaotic. The space used at the gate could not cater for the number of passengers and there was no way anyone with any priority boarding status could make it to the counter. This is not new and has been a recurring problem with this flight and turkish airline does not seem to care enough to handle.

Although we departed late from Paris, it arrived on time to Mexico City. Most of the stewardess very professional and kind.

Although we traveled in Business, all business cabins were full of children, tired crying, walking around. My suggestion to AIR France would be that the small cabin of business were assigned to adults only. Regarding food, some options were not available when our turn came.

Initially the flight from Lima was delayed for almost 1:30 and then we lost this connection then Airfrance rebooking to SAS they tell us to take all our luggage’s and check in again it’s was awful and really bad from then walk and spend time we suppose to be quite at home ... the worst was in SAS have ano system and for 1.5 kilos extras you might pay 33€ so after long day and wait, running everywhere with all my staff I see to eat a 11€ menu at the airport with not more explanation from Airfrance .. really bad and worst services..

Delta has great seats, friendly employees and engaged managers and pilots. Even their customer service Center reaches out to help on suggestions. I am flying to Portland for School over 40 round trips and I am saving $4,000 vs Alaska Air. Plus I get miles and discounts with the Delta Amex Card. I am very pleased.

I don’t like harsh change in schedule fees but it forces me to plan. I wish the Seattle to Portland Eve flight landed in time to catch Portland Rail system at 11:50 PM
