A few bugs that I noticed:
1. When looking for availability with 1 adult selected, if I change any search values, I get an error saying that I must select at least one adult. Hitting search again results in the correct results.
2. In the "new" BAEC booking page, if one selects book with cash and upgrade with miles, the combo box that selects the booking class is labeled as flight class which is bloody confusing!
HTH,
Rod
