Can you bring me a glass of water?
bic-CHIE-re — stress on second syllable. The double 'cc' creates a harder 'k' sound.
During the flight when you are thirsty and want to ask cabin crew for water.
'Potete portarmi' (can you bring me) uses 'potere' in the second person plural — addressing the cabin crew collectively. 'Portarmi' is 'portare' + 'mi' (bring to me). 'Bicchiere d'acqua' (glass of water) is a very common request on any flight.
Posso avere del succo di frutta?
Can I have some fruit juice?
Common alternative to water — orange juice is most common
Avete caffè?
Do you have coffee?
Italians will seek coffee even at 30,000 feet
Una Coca-Cola, per favore.
A Coca-Cola, please.
Stating your order directly is also perfectly natural
Staying hydrated on flights is important as cabin air is very dry. Water is generally free of charge on most European flights, though budget carriers may charge. Italians have a strong preference for still water ('naturale') over sparkling ('frizzante'), though both are widely available.
