before changes my title was "cheap flights New York to Abuja" some suggest me that
change "cheap flights New York to Abuja - FlightOm" but position dump. please help me guys

Look at your backlink profile

It's unlikely that the drop was because you changed the title, because you didn't really change it dramatically.
What else did you do to the site?

-- I suggest you to unbold some words. I checked your web page it's like 50% text is bold lol,
-- also I if you can change the meta description then change it and use your targeted term only 1 time.
-- if You can add up fresh content 1 or 2 para then add it and resubmit your sitemap.
-- if you don't see positive changes in SERPS

then You should at your recently created/indexed backlinks..

I don't have a clue about your rankings, but on a site note, I'd advise you to fix the typo:



It's quite eye-catching.
