"Excuse me" is the best way to get someone's attention, especially if you do not know them. From there, you can simply state that you did not receive a meal. The flight attendant should understand and then ask you which of the options you would like.
I hope that this helps! :)
例文１は直訳すると「まだ機内食を配膳されていません。」＝「まだ機内食をいただいていません。」
serve で「（食事を）出す」
in-flight meal で「機内食」
in-flight meal を meal だけにしても問題ありません。
例文２は直訳すると「だれか私の食事を忘れたようです。」＝「まだ機内食をいただいていません。」
I think somebody may have forgottenと言うことで「忘れられてるみたいです」となります。
I don't think I've been served the in-flight meal yet.
「まだ機内食をいただいていないようです。」
とも言えます。
ご参考になれば幸いです！
Hi, I think you missed me in the meal service, would you have another dinner/lunch there?
When we don't receive our meals on the plane it can be quite distressing. Asking the crew for a meal is easy and straight forward. It is always good to remember they are there to help you. :)'
You can be polite and say - "Excuse me..." when you want a crew members attention. You can then go onto say "...I didn't receive my lunch/dinner." The crew will get one for you. Or you could also take the pressure of the crew and frame it as if it was a total accident that they missed you.
You could be feeling quite cross/angry - "Sir, I haven't received my meal. I would like the chicken now."
飛行機で食事をもらえないとストレスを感じますね。搭乗員に食事を頼むのは簡単です。ストレートな言い方でお願いできます。搭乗員の人たちは私たちを助けるためにそこにいるわけです。
搭乗員の注意をひくときには、丁寧に「Excuse me...」と言えます。それから、
"...I didn't receive my lunch/dinner."（ランチ／ディナーをもらいませんでした。）
と言えます。搭乗員は食事を持ってきてくれるでしょう。
ほかに、自分が抜かされてしまったのは完全にアクシデントだったと表して、相手にプレッシャーをかけないようにすることもできます。
かなり腹を立てているかもしれませんよね。そんな時は：
"Sir, I haven't received my meal. I would like the chicken now."
（すみません、食事をまだもらっていません。今すぐチキンを持ってきてください。）
Excuse me; I think you might have forgotten to give me my meal
When the cabin crew forgets to give you your in-flight meal; then you may remind them in the following ways:
-I still have not received my meal yet.
-Excuse me; I think you might have forgotten to give me my meal
客室乗務員に忘れられて機内食をもらえなかったときは、次のように言えます。
-I still have not received my meal yet.（まだ食事をもらっていません）
-Excuse me; I think you might have forgotten to give me my meal（すみません、まだ食事をもらっていません）
To get someones attention then the polite way is to say 'excuse me'
If you have been given something (got it) then you can also say you have 'recieved' it
To let the person know that they have forgotten you then you would say 'sorry but I think you have forgot my meal'
人の注意を引くときの丁寧な言い方は 'excuse me' です。
何かをもらう（given／get）ことは、'receive' でも表せます。
忘れられたと伝えるなら、'sorry but I think you have forgot my meal'（すみません、私の食事を忘れませんでしたか）と言えます。
"I still haven't received my meal yet"
To 'Receive' something is to be given/presented something.
"I believe you had skipped my meal"
To use the term 'believe' is to think something, a more formal and polite way of phrasing this.
'Skipped' is used when something has been missed or looked over.
"I still haven't received my meal yet"（まだ食事をもらっていません）
'Receive' は「もらう／与えられる」という意味です。
"I believe you had skipped my meal"（私の食事を飛ばしませんでしたか）
'Believe' は「～と考える」という意味です。'Think' のよりフォーマルで丁寧な言い方です。
'Skipped' は、何かを抜かしたり見落としたときに使われます。
