The most useful lucky synonym is fortunate: it fits almost every sentence and sounds a shade more polished. Close behind are blessed, fortuitous, timely and the casual in luck.
Lucky describes two different things. It can describe a person who has good luck (a lucky winner), or an event that happened by good chance (a lucky break). Some replacements work only for people and others only for events, which is why people and events get separate lists on this page.

Tone check: in luck, fortunate, fortuitous
On the strip near the top, the words move from casual to formal. In luck is spoken English: "You're in luck, we have one left." Fortunate lifts the tone slightly above plain lucky and works in emails and speeches. Blessed adds warmth and, for some readers, a spiritual note. Providential is formal and hints that fate or faith arranged things. Fortuitous is formal and is mostly used for events that turned out well by accident.
British speakers also say jammy, often with a teasing edge. It is too slangy for writing.

Luckily, luckier and the noun luck
For the adverb luckily, try fortunately, happily or as luck would have it. Fortunately is the safe opener in any register.

Swaps that miss the mark
Happy works only in old fixed phrases like a happy accident. Saying "I am happy" does not mean you are lucky. Successful credits skill rather than chance, so it changes the meaning. Rich and wealthy describe money, not fortune. Privileged can work, but it often implies an unearned advantage from birth or class, so it may sound critical.
