The award KLM flights have all disappeared. Maybe it was a glitch or miscommunication. I ended up just finding a flight from SEA to LAX to LON.
Next question. I am going to book two separate flights instead of using LON as my connection bc BA was $327 to AMS instead of AS/AA's $19 to LON. Now, I need to book a flight from LON to AMS and will book either BA or KLM. Am I going to need to check my luggage and go through airport security again? Would 2 hours be a sufficient amount of time to catch the next flight?
Thanks again for all of your help and advice!
