It was my best ever transatlantic flight for flight attendant kindness and caring service.

Seats are EXTREMELY uncomfortable on the 767 plane. Wish Delta flew a 777to London.

It's such a pity that you are now charging for bags for international flights. It may be slightly passable for domestic flights. Economy coach is tough enough with the small seats but baggage charging for an international flight is disappointing - particularly when I am travelling with a toddler. Delta can do better - even for us schmuks in economy.
