With regard to American Airline we have had problems the past 4 years using our mile , two years ago it cost us 70,000 miles each to travel to SXM not in high season ,but in late October that was the last time we used AA . We had only used AA for all our flights to were ever we flew , dought we will ever use them again . Now we have Captial One Adventure card we pick the flight and away we go no hassle .
