You're asking if you can use travel bills from January 2018 to make an LTA claim for the financial year 2019-20. While generally you cannot claim for a previous year, if your LTA block falls within 2018-2021 and you haven't used both allowed claims within that four-year period, it might be possible. However, it's important to confirm if your current block has already ended.

Thank you sir. But a query, the travel and claim comes in same block of 2018-2021 And can claim 2 travel. And the act does not give any restriction of travel dates.
