On the Plane

bebakhshid, sandali-ye man kojast?

Excuse me, where is my seat?

Safe opener with any crew member or fellow passenger.

sandali-am inja-st?

Is this my seat?

Short, natural check when you think you have found your row.

komak mikonid chamedanam ro bezaram bala?

Can you help me put my bag up there?

میکنید is polite plural; کمک میکنی works with a fellow passenger you are already chatting with.

ja tu-ye havapayma tange — mishe komak koni?

It's tight in here — can you give me a hand?

Use only with a passenger sitting nearby, not with crew.

ye livun ab, mamnun.

A glass of water, please.

Minimal and perfectly natural; ممنون at the end is enough politeness here.

mishe ye patu biyarid?

Could you bring me a blanket?

میشه + infinitive is the standard polite request form with crew.

kamarband ro key bayad bebandam?

When do I need to fasten the seatbelt?

باید + subjunctive signals obligation — appropriate for a rule question.

cheragh-e kamarband rowshane — bayad bebandish.

The seatbelt sign is on — you need to buckle up.

A passenger might say this; crew would phrase it more formally.

bebakhshid, mishe ja-tun ro ba man avaz konid?

Excuse me, would you be willing to swap seats with me?

جاتون رو عوض کردن is the everyday idiom for seat-swapping.

mitunam ba shoma ja avaz konam? pish-e bachche-am beshinam.

Can I swap with you? I want to sit next to my child.

Giving a brief reason makes the request much more likely to succeed.

halam khub nist — ye kise darid?

I don't feel well — do you have a bag?

کیسه (bag) is the discreet everyday word; crew will understand immediately.

saram dare micharkheh, mitunam deraz bekesham?

I'm dizzy — can I lie down?

Useful on a long-haul flight with empty rows; crew can assist.

ye ghors-e mosaken darid?

Do you have a painkiller?

Crew carry basic medication on most commercial flights.

in sandali kharabe — poshtish nemire aghab.

This seat is broken — the back won't recline.

Report to crew; they may move you or note it for maintenance.

cheghadr ta maghsad munde?

How long until we land?

مونده is the casual spoken form of مانده — perfectly natural here.
