My parents and I headed directly for the United Club located at the E gates. Lunch food were setup already when we arrived and I helped myself to some soup and nibbles.

This club has 3 levels. 1st floor is check-in and the other two floors are for the club. We started out on the second floor but moved to the 3rd floor which was much less busier. Great view of the activity on the ramp from the club.

During our stay in the club, a massive thunderstorm rolled into IAH. With the amount of rain, we were worried about delays, but nothing major.

We headed out to the gate for our Lima flight. It turned out, that our gate has an automated gate system. During boarding, this did not work so boarding was processed manually.

The problem with gate E4 is that you can't see your plane.

That is all you can see.

Had the same FA greeting passengers at the door on our way back.

Full size pillows! Why can't other airlines do this as well?

Lots of activity outside.

Before they could close the door, we had to wait for people connecting from the NRT flight.

After takeoff, hot towels and immigration forms were handed out. Our aisle was being worked by one of the BEST FA's I've ever flown with. She was cheerful and I felt like she genuinely enjoyed her job. It was really refreshing to have a "human" FA than always dealing with the forced smile of foreign carriers. Actually all the FA's on our flight were great.

God bless her she also thought I was in my mid 20's and was shocked when I told her I was in my mid 30's.

Beverage and dinner service started shortly. Table cloths were placed on my traytable vs being handed to me as others have mentioned in previous reports. Drinks were constantly refilled, and empty dishes were prompty removed and all done with a smile! My mom was too tired for dessert but I was determined to have dessert before bed.

Out of ALL the business class seats I have slept on. United's was the most comfortable and I got the best sleep ever on an airplane. Reclined 180, I did not feel any lumps or pressure points and with the large pillows, woke up just before snack service feeling really refreshed.

When I woke up, there were two bottles of water on the center console.

Pre-arrival snack service started with more hot towels and another tablecloth.

Snack was a cheese plate.

Landing in Lima was uneventful and due to the small size of the airport, be were at the gate like 2 min after touching down.

Having avoided flying United Internationally due to reading so many bad reviews, we ended up flying United due to no other reasonable option getting to Lima from LAX on a Star Alliance carrier. There is Avianca and Copa which both involved multiple connections and really really tight transfer times. We expected the worst but ended up quite pleased with the service and comfort provided by United.
