「遅れる」を英語で表現する方法はいくつもありますが、「[早まる](https://eikaiwa.dmm.com/uknow/questions/65974/)」を英語でどう表現するかは少し難しい問題ですね。
【主な表現】
1. My flight was moved up a day.
2. My flight has been rescheduled to a day earlier.
3. My flight departure was advanced by a day.
これらのフレーズはすべて「私のフライトが1日早まった」という意味になります。
特に表現1 "`moved up`" は、イベントや計画が早くなった、つまり前倒しになったことを表しています。ちなみに逆の意味、つまり「遅らせる」は "`moved back`" となります。
また、3番目のフレーズに出てくる "`advanced`" という単語も、「進める、早める」を意味するので、予定が早まったことを表現するのに役立ちます。
なお、これらの表現には"has been"の形を使うことで完了形を作ることもできます。これは特に、すでに予定が変更になった後でそのことを話すときに役立ちます。例えば:
- My flight has been moved up a day.
- My flight has been rescheduled to a day earlier.
なお、これらの表現は一般的で、航空会社によるフライトの変更だけでなく、予定全般が前倒しになったことを表すのにも使えます。
以上の情報が参考になれば幸いです。"
トリー先生に付け加えて 早まった は次のようにも言えます。
be brought forward
be advanced
どれも「[前に](https://eikaiwa.dmm.com/uknow/questions/60688/)動く」という意味を含んでいますよね。
My fright was brought forward a day.
My fright was advanced a day.
([フライト](https://eikaiwa.dmm.com/uknow/questions/55881/)が一日早まりました。）
My flight was cancelled and I'm leaving a day earlier than planned
I decided to take an earlier flight
Yes, some may call it rescheduling, but really, that is a cancelled flight. You are simply taking an earlier flight - in the case of the airline arranging this. However, as you don't mention who is rearranging the flight, it could be that your boss or even you, yourself have done this. In that case, it could be a 'rescheduled' flight....or a rescheduled itinerary. Or you could just say:"I decided to take an earlier flight."
はい、reschedulingと呼ばれるかもしれませんが、実際はフライトキャンセルです。これを手配する航空会社の早いフライトにのるということですね。しかし、フライトをどのように予約しているかについては言及していないので、上司、あなた自身がこれを行っている可能性があります。その場合、それは a 'rescheduled' flight.といってもよいし、あるいは、"I decided to take an earlier flight."と言うこともできます。
My flight date has been rescheduled to Thursday, a day earlier.
My flight date has been moved forward a day earlier from Friday to Thursday.
Sometimes airport management do change travelers' travel schedules due to some reasons such as availability of seats or overbooking on certain flights. This may cause them to randomly reschedule some passengers' travel dates by moving them to either earlier or later flights depending on the situation. This may either be advantageous or disadvantageous to the affected passenger. Whatever the case may be, you may say:
My flight date has been rescheduled to Thursday, a day earlier.
or
My flight date has been moved forward a day earlier from Friday to Thursday.
航空会社は時に座席予約状況やオーバーブッキング等の事情で乗客の旅程を変更することがあります。この場合、ある乗客の搭乗日が早まったり遅れたりします。変更に遭遇した乗客にとっては迷惑だったり、ラッキーだったり様々でしょう。どのような状況であったにしろ、下記の表現を使うことが出来ます。
My flight date has been rescheduled to Thursday, a day earlier.
（私の搭乗便が一日早い木曜日に変更になりました。）
My flight date has been moved forward a day earlier from Friday to Thursday.
（私の搭乗便が金曜日から一日早い木曜日に変更になりました。）
I flight was moved up from 8pm to 6.40pm this evening.
You can use the phrasal verbs "moved up" or "brought forward" to show that something that was originally at another time or date has been moved closer to the present time.
Example: "The meeting was moved up from Tuesday to today."
You can use the following sentences to express yourself:
1)My flight date has been postponed to Thursday.
2)My flight date has been moved to Thursday
3)My flight date has been rescheduled to Thursday.
こういった表現ができます
1)My flight date has been postponed to Thursday.
飛行機の日が木曜日に延期された。
2)My flight date has been moved to Thursday
飛行機の日が木曜日に移動した。
3)My flight date has been rescheduled to Thursday.
飛行機の日が木曜日にリスケされた。
My flight is going to leave a day earlier than scheduled.
My flight was rescheduled to one day earlier than the original date.
If you would like to tell someone that your flight has been brought forward a day, you can say something like "My flight is going to leave a day earlier than scheduled." or "My flight was rescheduled to one day earlier than the original date.". These are some easy ways to say this.
Examples:
My flight got moved forward one day, so now I am leaving next Tuesday instead of next Monday.
My flight got rescheduled, so I have to depart a day early now!
My airline moved my flight forward one day, due to scheduling issues at the airport, this time of the year is very busy for people who want to travel!
In the first and third example, we can use the verbs, "moved up," or, "brought forward," interchangeably to have the same meaning within the phrase. Within the second example, we can be more specific to talk about which dates to show this move forward in days.

おっしゃられている内容は、想定している文脈にもよりますが、
I have to leave a day earlier.
「私は1日早く出発しないといけない」
のように表現しても良いと思います(*^_^*)
