However, in both dialects it often sounds closer to /a/ before /l/, in words ending with "-ality" like reality, personality etc. because the /l/ "colors" the preceding vowel (this can also be seen with other vowels in American English, like /ɑ/ or /ʌ/ becoming closer to /ɒ/).
Additionally in American English /æ/ often becomes /eə/ before /n/ and /m/ in words like pan, dam etc.(and in some dialects is always /eə/), and can even become /eɪ/ before /ŋ/ in words like thanks, bank etc.
