Here's a nice method for Firefox
Outcome
You enter "ba XXXXXX" in the address bar (CTRL+L shortcut takes you straight there) where XXXXXX is your booking ref. Firefox takes you straight to your booking.
How to do it
Create a new bookmark
1. Give it a name (e.g. BA booking)
2. In the
Location box, enter
http://www.ba.com/mmb/3?bookingRef=%s&lastname=YourSurname[/url]
NB Don't include that [/url] bit: I had to add it so that the full url is displayed
3. Set the
Keyword to ba
4. Click OK
