Food was all tasty. Liked the ice cream treat. Was surprised because flt going to Europe was on BA and all the food practically uneatable.

The choices of movies and music was very dated and I h Found it hard to find anything to view. Lots of dark, scary or violent choices. Would of preferred more lighthearted choices.

Took very long for baggage to arrive. I guess it was more noticeable in San Diego as they want one to collect bags before border control unlike other airports. Treated well throughout. Great connection experience in Heathrow.
