We fly boston to london heathrow once or twice a year. usually with miles on American. American is now using planes that are 3/3 seating. rather small. no entertainment center, etc. were using 2/3/2 also no entertainment center.

with the recent volcanic activity this week they are not flying at all. BA and Virgin are. - must be going around.

If we switch to BA and start accumulating miles on their plan- (thru starwood). what can we expect re planes and understand the fees are much? higher on tickets bot with miles? why? since both land at heathrow.

any info would be helpful.
