How reliable is Trip.com for international travel

So ill have to travel to US to meet my spouse. Due to the ongoing situations its becoming difficult to look up for any flights via Gulf as there's a high chance of cancellation. Looked up in Trip.com for some affordable prices via London. And travelling from India btw. So how much is it trustable and worth booking, and pls do let me know if there are any other suggestions or recommednations. Planning to travel in the end of March
