My husband's luggage was lost even though it was checked in at the same time as mine. It was eventually located and was shipped to a municipal airport in the area where we are heading. We have yet to be able to pick up the suit case as we will be heading to the pickup location tomorrow. ( 4 days after arrival) We had to buy some new clothes and shoes for my husband in the meantime. I think I should be reimbursed for the baggage check fee. We lost time at the airport upon arrival trying to track our luggage. We lost time and money having to purchase clothes and shoes while waiting for luggage to arrive and we will lose time having to drive 2 hours out of our way to retrieve our luggage.

The new check in process at Newark liberty airport was so efficient. Did have a bit of a bottleneck situation at security. Flight was on time, boarding was smooth. Friendly crew.. excellent communication from pilot about nature of delays. I am slightly hard of hearing and I think due to the poor quality of headphones i had to turn it up much louder than I should have.. it made it uncomfortable. It would be great if that was a priority. Impressed with main course but don’t like quality of buns.. I much prefer bread made with wholesome unrefined flour. Very happy with biscotti and the quality of yoghurt provided for breakfast!

Unfriendly staff, the pilot never announced anything during the entire flight including we’re at altitude, what the weather was like at the destination how much time is left if we were ahead or behind schedule etc. Very funny gay gene flight crew.
