Pros: I really like the preferred seating area and the crew overall
Cons: Boarding was communicated by areas one time only. I would suggest to repeat communication of the areas that were told to board before so if you missed the first one you don’t have to wait until the end

Pros: That I got to visit a place as mystical as Iceland for such a low and affordable flight. My departure flight with Iceland Air was on time and although the return was a bit tardy the company did an excellent job with being transparent.
Cons: The flight crew could have been a bit more polite

Cons: Sarasota ticketing agent was not very nice at all 😟 Houston Gate agent was not nice either. We were treated like we were stupid for asking questions. I hope it’s not racism issues. I wished I had taken their names.

Pros: Customer service by the crew
Cons: Lufthansa still charges full price like usual, but on a 8+ hour flight to serve a cat size meal of pasta soaked in some pesto sauce is unacceptable! Thank god I had lunch at Frankfurt before departure! Covid-19 should not be an excuse for lack of services! I work for a company which falls into the Essential business category and despite the pandemic we NEVER EVER compromised with the top quality of our product! I am so dissatisfied with Lufthansa and what they have become, pale shadow of a great company, very sad....

Pros: Although there were delays they kept us informed on a regular basis as to what to expect and seemed genuinely apologetic for any inconveniences. Boarding and deplaning were smooth and efficient. I really appreciated that there was no charge for checking a bag. I am certain that contributes to the ease of everyone getting on and off the plane. Our bags arrived at baggage claim about the same time we got there. I would definitely fly with Virgin Atlantic again.
