Dears,
I am selling my British Airlines E-Voucher because I canceled my flight from USA, Houston to LONDON in December 26, 2021. The reason of cancelation is that I was not sure about the situation of the pandemic at that time of the year, so I preferred staying in the US rather than traveling.
If you are traveling using British Airways feel free to purchase my voucher and you will save more money than the regular priced tickets since I am willing to sell my voucher cheaper than its value.
