Can anyone suggest a good rate to fly from London to Bali with a stopover at bangkok.

Time of travel: April 29th
return: May 10th

If Bali is not possible, then please advise on a ticket to Bangkok. Is there any sites that offer packages from London also.

Fromers etc etc all seem to offer packages only from the US but nothing from UK. I al looking at hotels also besides air. 4 days in Bangkok and 5 in Bali.

Please advise
