I hope there’s a complimentary wi-fi during flight if no entertainment is available. Also, the cabin is a little bit warm during the flight and it’s also late but I’m not worried about 20 mins late. It’s more of comfort I guess but the crews are awesome. The pilot did an amazing take off and landing.
