Overall the experience was good. First flight of 17 hours had no entertainment since Singapore airline has technical issues. Was informed that passengers would get a $350 voucher for future flight. Uncertain how that is being distributed but would like to understand if an email is required from my end or if it is an automatic email sent to me by Singapore Airlines. -Gina Robles
