My complaint:
The following day after arrival in Sydney, a had large itchy raised welts erupt on both legs just below my buttocks.
Today 25 June these bites are still raised, red and sore.
I have reason to believe that these are the result of a bedbug infestation of the seat(s) I occupied on this 14 hour flight from Doha to Sydney
Suggested solution:
Check seats for possible infestaion
